Was driving to work. Got 2 miles down the freeway in stop and go traffic. My tj shut off while going like 10mph and wouldn't restart. No codes. 3/4 tank gas. Battery holding charge we even tried to jump it just in case. Does not crank or turn over. Dead silence. Have not had any issues in the last 2 years of ownership. I'm thinking starter or alternator? What you guys think?
I am thinking, since it died going down the street, that it could be the alternator. Once started, the alternator should handle the load of the electronics on a running jeep. This is why you should be able to start a jeep, remove the battery, and it continue to run.
As for the starter...I know when mine crapped out, I was able to tap on it firmly and it would engage and start up. I dont know why a starter would cause you to die goin down the road though. If you can get the jeep down to an auto store, most of them can test the alternator in the vehicle. They may be able to test the starter still installed as well. If not, I know you can take either of them inside and test them.

Check the connections on your alternator. The battery can have enough power to keep the bells and whistles going but not enough to turn over the engine. I would check the ignition cables to make sure that everything is good and tight with no corrosion or breaks. Also look for loose ground wires that could be draining your electrical system.

My guess would be ignition cylinder or sensor related....neutral safety switch? Try going from park through all the gears, wiggle it around ,try starting in neutral. You could also try jumping the starter I think that bypasses the switch.
Do a quick search for ignition switch actuator pin part # 924-704. Mine broke Monday when it was below freezing and had a similar no start condition like the starter or battery was bad. Its a very common issue with Mopars including Jeeps. If you must start the Jeep you can pull the starter relay located in the PDC under the hood and use a jumper wire from terminal #30 and #87(my jeep is a 1998 so maybe double check!!), as soon as the Jeep starts quickly pull the jumper wire out replace and replace the relay.
EDIT- You will need the key in on position and a helper to hold the brake for it to start with a jumper or I think you will need to bypass the neutral safety switch. Mine is a 5 speed and I was by myself so I threw a 20a fuse in slot #20 to bypass the clutch safety switch.
Check connections on the starter solenoid. Pretty sure (not 100% but hopefully someone will chime in) that all the power (except for accessories) runs through it, so if a connection on the solenoid fails then not only will your starter not work, but your motor will die as well.
Im not completely sure of that but if nothing else has worked yet...might take a look
