If it starts with the engine COLD, but won't start with a hot engine, then the crankshaft position sensor is suspect. It can suffer from thermal (heat related) failure. If you replace it, buy a Mopar crank sensor directly from Jeep. Aftermarket crank sensors are "hit and miss" with a lot of miss.
Another possibility (although less likely) is the ignition coil.
