Q: serious misfire to complete stall-5 minutes rest=re-starts and runs fair to good=why? on 2001 Chrysler PT Cruiser

43,586 trouble free miles. Car misfires and goes to complete stall. Rest for 5 minutes and will re-start. Runs fair and advances to good for indefine period. Returns to problem. Runs good at shop and no trouble diagnosed. Once had to be towed and then replaced crankshaft position sensor. Back to same problem=unpredictable stalling. In desperation have changed plugs, ignition wires, ignition coil module. Got 6600 O>K>miles and now back to the same problem. Any suggestions?

if you havent already figured it out , you could have someone check the fuel presure ,, youre fuel pump might be going bad ,, i have had the same problem with other cars / hope this helps
If your vehicle was repair by replacing the crankshaft position sensor before, then possibly the sensor has failed again. I've replaced three crank position sensors on my truck in 232,000 miles and when it acts up I know to replace the sensor.
It's been month's since you posted your question. What did you end up doing to fix the problem? I am having the same problem and have had my sensor replaced twice. Please advise.
this is a common problem...what we have found to be the case is that many aftermarket
crank sensors fail over and over....after several failures and checking tooth clearance.
build up at mounting area, distance from crank to sensor, bla bla bla.... the car just
dose not like aftermarket sensors....replaced the problematic cars with OEM sensors and
walla no problems.....hope this helps
when you remove the crank sensor see if there is rust biuld up on the engine block preventing the sensor from sitting flat on the block.This well put the sensor further away from the crank shaft timing wheel and at higher engine speeds may not allow the sensor to pick up the timing marks
