Have replaced plugs wires cap rotar

Dies going 60, 30, or at a stop sign with no indications like stumbling or running out of gas. Radio and power remain on, just the engine dies. What I have done: Changed distributor, cap, rotor, plugs, wires. Tried 2 different pcm's, changed sensors: tps, iac, map, crank, cam. Has a new battery, alternator, fuel pump, coil. Checked engine grounds, shot wires to all sensors - continuity and to ground. Verified all relays and have swapped them out. At my wits end. Dodge dealer and another mechanic could not find anything and didn't even have a suggestion. I have basically changed everything every forum suggests, this problem is very common if you go through all the forums and they suggest many fixes, none of which has worked. Thought I had it fixed, but it died again on the highway, help! No codes ever show up on this, dealer verifed no codes also.

I recently purchased it put a rebuilt computer in it to get it running the van sit for about a year before i purchased it. Ive been told that the pcm could have something to do with the problem. Ive put some marvels mystry oil in it thinking it might have some sludge build up in the screen. I took thevalve covers off only to find motor fairly clean for 85000 miles can u give me some ideas with this problem

As I have some mechanical experience, I am a driveway repairman. I need some reasonably detailed advice, as the Hanes Dodge repair manual does not address this subject.
Thank you.

Changed Camshaft Position (CMP) Sensor.
Changed Air Intake volve Sensor

a ballpark price on how much it will cost me.

turn the key and all the lights come on but starter does not engage. is it the ignition switch?? it works sometimes but less and less often.

i can drive it for half an hour and once I shut it off it takes about 45 minutes to get it started again

How do you take the dog house off, so I can do a tune-up.

I replaced and rechecked the gap and plugs which are fine, but the 135 show a misfire. I replaced the thermastat & radiator as well all with in the month. Now it bogs in morning starting for ten minutes and then is fine.
