Thanks for the advice. Today I swapped the Oxygen Sensors (I'd been getting occasional Check Engine warnings about them periodically over the last year, but it would go away every time after a few miles) but it didn't make a difference. 5 miles into my test drive, it stalled out, then again on the way back.
I've checked and secured all the grounds, built the metal bracket to hold and support the plug banks even though wiggling them made no difference, and now replaced the two known problem sensors with no luck. I guess I'm really at the point where I have to swap the PCM or break it open and see what's inside I might be able to clean up or repair.
I'm really surprised that there's so much activity and folk remedies for this issue, but apparently no word from Chrysler over the years.

Try replacing your coil wire and the coil, unless you have a coil for each cylinder. Check the spark before you replace the computer. Get an RMS voltmeter and backprobe the fuel injectors. If you get no reading, you found a problem. The computer sends electrical pulses to the fuel injectors. That's why you need an RMS voltmeter. A regular volt meter won't measure very well, if at all. If you are getting pulses at injectors and spark, I doubt your computer is bad

I have been having the same problem with sporadic stalling, and starting issues. Replaced ICU, TPS, MAP, COIL, ROTOR, CAP. After getting stuck several more times I found a loose plug at my CPU. i jammed a piece of cardboard against it and the antifreeze resevoir. Runs just fine now. I found out the connections are well known for comming loose even though they look fine.

hey i had the same thing going on and i found out this even if you get psi on the gas line when its spitting look at the gas make sure it is holding psi. i learned by watching mine works good than as soon as it started spitting that the psi was also dropping very little it was my pump going bad in fact every one told me that if it was the pump it would not start at all i also read that some jeeps have screws that are to long in the cumputer making it short i dont know that but i fixed mine with fuel pump 1999 cherokee larado
