A sensor or solenoid is warming up, then going bad.
Check all your sensors cold, then warm, the one that goes out should be obvious, im leaning towards map (vacuum) sensor. CHECK YOUR INJECTORS AND FUEL PRESSURE TOO!
Regardless it sounds like your Jeep is running way lean when it warms up, losing a ton of power causing your stalling issue.
There is nothing wrong with your clutch or transmission.
Your best bet is to take it to a mechanic that knows these vehicles, most shops will avoid it, unless they employ a Jeeper, or Chrysler tech.
