2000 Jeep stalling while driving

I have a 2000 Jeep GC Limited with 96000 miles on it. I have recently had it in the shop for some transmission work. It was in limp mode and it took them four weeks to get it fixed. They tried some relays, solenoids, a new TCM, and some wires in the wiring harness. When I picked it up from the shop, the transmission was working, but the ABS light was on. Didnt worry, as i would rather have the ABS light on rather than the check engine light and the tranny in limp mode. Now the Jeep is stalling while driving, and wont restart for about 5 minutes. I live in Vegas, so being in a dead car in the summer is a bad idea. Any ideas? thanks for any ideas.

try the Crank sensor, Throttle Position Sensor, and take coil off and look to see if it has any hotspots in it!
