1998 Dodge Dakota Question: Truck Shuts Off

I have spent nearly $3k in repairs on my truck and just have had my PCM replaced for the third time. The truck ran fine for three days. After driving for about 5 miles yesterday at highway speed (50-55mph), the truck just shut off. I pulled over, cranked it back up and it ran fine. 5 hours later, cranked it up and it shut off about 10 seconds later. Did this three times before it would stay cranked and I could drive it. I have had this truck in three different shops having thousands of dollars worth of parts replaced (plus labor)...still the same problem. I am at my wits end. Any suggestions would be appreciated.

    Hello , well without looking at the vehicle myself , it is hard to say ,, the best thing to do is find out what is missing when the situation occurs , spark, fuel, power , grounds , ect .. Is there any codes stored in the computer??? just a guess , but did you replace the crankshaft sensor??

    I had the crank sensor replaced back on 09/24/2008...along with new plugs, wires, distributor cap, and ignition coil replaced. When all else failed, another ECM was installed. Then the repair shop replaced my catalytic converter because the check engine light would come on every other day saying there was a misfire between the 5th and 6th cylinder.
    Back in June 2006, I had a new pcm installed as well...and a new ignition coil and map sensor.
    The truck was actually running fine until I put it in the shop back on 8/11/08 to have new manifold intake gaskets replaced. Replaced valve cover gaskets and transmission front and rear seals replaced. The truck has not run right since...and turns off when it wants to. Usually just cranks right back up and might run ok for a few days before it starts to die on me again.

    OK, WELL IF THE TRUCK WAS RUNNING OK UP TO THE POINT WHEN YOU HAD IT AT THE SHOP FOR THE MANIFOLD ISSUES , THEN I WOULD HAVE TO SAY THERE MORE THAN LIKELY IS A LOOSE GROUND WIRE SOMEWHERE, OR SOMETHING WAS NOT TIGHTENED PROPERLY, LOOK FOR ANY LOOSE GROUND CONECTOINS , ON THE FIREWALL , ENGINE BLOCK, FRAME TO ENGINE , ECT ..

    ALSO I KNOW THAT YOU SAID THAT YOU HAD THE CRANK SENSOR REPLACED , HOWEVER IT HAS BEEN OVER A YEAR ,, WHILE THE TRUCK IS RUNNING TRY TAPPING ON THE CRANK SENSOR , SEE IF THERE IS ANY DIFFERENCE IN THE WAY THE TRUCK RUNS WHILE DOING SO.. ALSO INSPECT THE WIRING GOING TO THE SENSOR ITSELF , MAKE SURE NO WIRES ARE RUBBING ON ANY BRACKETS , ECT ..

    Thanks for your time and advice. I will relay this information to the shop where my truck is now first thing Monday morning. I also sent an email to Dodge today and will be talking to them next week. This truck is my main source of transportation and I have not cut any corners in trying to get this truck fixed...but I am running broke paying for repairs and parts that seem not to work. Again, thanks and I will let you know what happens next.

    Thanks,

    Neil

    I meant to come back a whole lot sooner to thank you for your help. I had the crank sensor replaced and the truck has been running without stalling, cutting off, or acting possessed since.

    But...I do have a new problem:

    My dash illumination lights went outlast week. Two days later my hazard flashers, turns signals, and rear lights went out...although my brake lights work. I replaced some of my fuses inside the truck, but getting no results. Any ideas on what to try next? Thanks for your help!! Neil

    My truck would randomly shut off at almost any time at any speed. It would usually restart after sitting for a while. No codes. Changed computer didnt work.Haynes service manual has very accurate electrical diagrams right down to the proper colors.Anyway, I determined it to be an electrical problem because only three of the four wires that supply power to the computer had 12 volts.One did not. Traced the harness and "that" wire all the way around the firewall(removing the jacket and tape on the whole thing) to find a FACTORY solder connection buried in the middle of the harness over near the battery that was green,corroded and barely making a connection. Sometimes it allowed 12volts sometimes it didnt. Restripped the wires and wirenutted the connection no more problem EVER!!!Cost of fix besides my time was zero. Took about 1 hour to trace out. Hope this helps.

    i have a 97 dakota and in the past year over 1900 dollars in repairs pcm replaced twice and somewhat same problem i was pretty upset i had no problems with it till the day i paid off the 15000 dollar loan but my truck was doind what you say yours is and one day i pulled in the driveway it stalled and every bump id hit the check engine light would flicker. turn the swith in the on position and grab a handfull of wires and wiggle em around i did and turns out at least 500 bucks couldve been saved had i done this in the first place it was a loose connection on the crank position sensor i would hear clicking and dinging from the check engine light coming on when i hit that harness and i was able to trace it down to the one fault and i too had my truck to three different shops and none of them were able to find the problem i do love my dakota and probably would spend forty grand to keep it on the road 15 grand for the loan and so far 6 grand on repairs in five years

    I don't know if you fix your problem yet,but I would check your fuel pump/regulator.I had a hard starting problem on my 98 and a new fuel pump/regulator fix the problem.

    I have a 99 Dodge Ram. My abs light, brake light are always on even though a code reader does not pick up anything. It worked wonderfully until 3 weeks ago. It died just died, without a check engine light on or anything.No bus was displayed on my odemeter and I replaced the CPS on it twice and checked all connections. It died again saying the same thing.It runs fine cold but when it heats up it dies. I think it may be my PCM but I dont want to replace that expensive part unless I know for sure.I checked all connections and wires nothing is burnt or charded or melted. If anyone has had this problem please let me know, and how you fixed it would be appricated.

    check to see if your wiring extremely hot maybe the heat is causing interference with you voltage which would cause you PCM to get a missed reading,check all wiring see if they are close to exhaust pipes if they are extremely hot try heat shield tape to protect them.

    Not sure if your still having the problem, but I have the same truck and very similar problems. I also spent unnecessary money to fix it. I have by trial and error determined on my own that it is a loose connection on one of the wiring harnesses on the computer. I'm almost sure your having the same problem. I've been dealing with this on and off for about 2 years. Good luck!!

    Its impossible to answer that without having the vechile before me, but from experience I've found out that dodge have a wiring problem, especial in florida where there is high quanities of salt in the air their wiring gets corroded. Had a Plymouth Voyageur,which kept stalling out one night it wouldn't start looked under the hood and notice some corrosion replaced the wires never had a problem since.They have great engines once you find one with electrical you got real problems.
