When it dies next time try to notice if the gauges work at all or if everything is gone including the fuel level. That indicates complete loss of communication between the instrument cluster and the PCM. Then pull the connector on the cam and crank sensors. If you still don't get gauges it's highly possible/probable it's a bad PCM.

If you're interested, PM me, I can likely get you a used PCM programmed to your VIN that's more likely to work than the hit and miss "remans"...
Thanks, OldWJs- It is at the shop right now. They are supposedly looking at it today, we will see what they say. If it comes to that, I will definitely PM you...

Sounds like what mine was doing. Stalling. No check engine light, no code using my scanner, but turning the key 3 times, and P0320 showed on the odometer.

Hmm.. didn't know that you could do that key trick- and P0320 is related to the crank and/or cam sensor, along with a few other things... interesting.

Mine is currently still in the shop. Mechanic has a scanner hooked up and is trying to get it to die while driving so he can see if any codes are thrown then. We will see...

They usually fail at random times. Easy to replace.

Some failure modes require it to be hot. I gently use a heat gun and an IR thermometer to get them up to temperature or you could just let it idle with the air conditioning on on a hot day.

Well, the mechanic finally got it to stall out while he had the scanner on it, and sure enough- P0320. Crank sensor. Had him replace it and it seems to be good now- although probably should wait to be sure, since sometimes it would go a couple days without stalling...

Thanks to everyone for the info and advice. I really appreciate it.
