Chrysler Repair: 2001 Chrysler Town and Country Van dying while driving, chrysler town and country, pulley bolt

Question
I have a 2001 Chrysler Town and Country Van (Limited) 3.8 L engine. Last Sunday I was driving to a town 170 miles away and about half way there it died while driving at a speed of 50 mph. I pull over to the side of the road and put it in park. I tried to restart the van by turning the key on and nothing turned over, the lights on the dash came on but nothing. I tried to move the shifter and it was frozen (I could not move it). It finally started after about 10 minutes. I then drove another 20 miles and it die again, this time it started in about 2 minutes. Drove another 14 miles and it died again but this time it took about 35 minutes before it would restart. I decided to drive back to the AutoZone in town to check the battery and alternator. Both checked good. The van die again leaving AutoZone, this time it started in about 8 minutes. We decided to head home instead continuing our trip so we left town heading back home. 30 miles out of town the van die again, this time it took about 5 minutes to restart. We drove another 50 miles and stopped for lunch without it dying. We drove the rest of the way home without it dying another 50 miles. I took it the next day to the dealership and they could not find anything wrong and yes there were no codes logged into the computer. Do you know might be the issue with this van ? Also we have replaced the electrical wiring harness about a year ago because we were told that the battery acid had corroded it.

Answer
Hi Anthony,
I wonder if one of your engine rotational sensors is going bad (camshaft or crankshaft) but not so badly as to set a code? You could get yourself set-up with a voltmeter and some pins with which to penetrate through the insulation of the signal and signal ground wires of those two sensors, and also a socket and ratchet handle to put on the crank pulley bolt, so that when it dies you can quickly check for the pulse voltage signal of each sensor by turning the engine over by hand when it is in the 'no start' state. The pulsed voltage should be between 5v and 0.3v as you turn the engine by hand with the ignition in the 'run' position. If not, then that would be the answer. About the only other thing that can shut down the engine like that is the egr valve if it sticks ajar say when you either accelerate or take your foot off the gas pedal as the mixture goes too lean to sustain an idle if that happens.
Let me know if you want to check out those tests and I will give you the details. That is my best advice for no start/no code situation that self-recover quickly.
