ok what it sounds like is that the alt is causing a draw and there for either the computer is shutting it down out the ecu is bad and shutting down the charging side of the alt. there is also an auto shut down relay but if this goes off the whole jeep would shut down I believe. take the ALT down to a auto part store and have them do a draw test on it.

Could be a failing alt. Mine was just weak. Can you take the neg cable off when running and if it stays running it's not the charge system. Dont reconnect negative cable until the engine is off. I had my alt. Tested by two different stores before I found it was the problem
