Default jeep shuts off when it comes to idle, wont start for 20-30 mins

I own a 98 Jeep Cherokee 4.0 auto. I've been wheeling twice now where my jeep has shut off once I've come to a stop. It does it so peacefully you can't even tell it shuts off. Then I have to wait 15-30 minutes until it will start back up. I don't have spark at that time either but I do have fuel pressure. Does this sound like a bad crank sensor? I'm getting no CEL either which is throwing me off a bit. Yesterday after I picked up some scrap, I shut my jeep off and it wouldn't restart for 15-30 minutes once again.

Sounds like the symptoms of a crank sensor. they fail when they get hot and then will work again when it cools off. There are plenty of threads about troubleshooting. If you replace it, I definitely recommend an original MOPAR. The lifetime warranty cheap ones are cheap for a reason.

My '00 was doing something similar and I believe the CPS was experiencing thermal failure too.
