Have replaced distributor and coil with new but still no spark. Was running when parked but would not start the next day. Determined no spark by in line spark testro. Replaced distributor and coil with new. Still no spark. Could it be crankshaft sensor or is there any other test for finding the problem.
Could be ignition control module. It is probably located on distributor. It is a black odd shaped object with like 2 or 3 plugs on it. Take it to an autozone and have it checked

It may be the brain of the jeep. if they get condensation in them from the rain , they can act as you described. It is only about a $30 part @ Pep Boys. It looks like a box with 2 or sometimes 3 plugs coming off of it and it plugs up to the wiring harness, and it mounts on the firewall or the inside fender-wall of your jeeps engine compartment.
Testimonial: "Thank you! I've replcd the ignition coil n battery. Won't start!Now, no fuel to engine. Still seem like it's the brain or PCM, ASD Relay or Fuel Pump?"

check your catalytic converter for clogged up.
disconnect the exhaust pipe before the cat and run the engine to see if it still cut off.
if it run better, then that's the problem
