This could be a couple things. First, take the jeep to a nationally recognized parts store and have them test the alternator / voltage regulator to make sure it's putting out enough power. If it is, check for loose or corroded ground straps. I believe there is one from the transmission to the under carrage of the car which is a common problem.
Let me know what you find.
