Jeep 4.0 shuts off

Daughter has a jeep cherokee 01 with auto and 4.0 ... in the past wek it has started acting up. driving along and it shuts off. Let it sit for a hr or so and it'll fire right up. Battery and charging system all checks out. plenty of FP. I'm thinking it's the coil packs but not 100% positive... any ideas or anybody run into this before?

Not sure if it has a crank shaft sensor. Our Marques did the same thing. It was dirty...after a cleaning it never did it again.

My 05' did the same thing after the stealership had to rebuild the engine for a recall.
come to find out the tards hooked all the plug wires up in reverse order (basicly makeing it run backwards) and fried the coil packs. Thank god there were able to reflash the CPU to get all the WTF [email protected] out of it. It was a miracle it ran at all. Yet to this day it still runs like a worn out lawnmower engine.
