I suspect the crank position sensor, very common in most cars, let alone jeeps, If you wish to do some prelimenary testing before changing it, a fuel pressure check and a spark check will indicate what area we need to go. If you find the spark is off, and that is what I suspect. Then I would be 99.9percent sure its the crank sensor
