OK I bought a 83 CJ7 with TPI 2 fall's ago got to drive it for about 2 month's before winter came then I parked it for the winter. Then once spring came around I was like Ill give it a tune up new plugs wires and cap it ran fine before and ran even better for the 1st week or so then it started acting up. Once it would get up to op temp then die I could even drive it 60miles or more before it would die sometimes it would restart right away and other time's it wont start for an hour or two. I thought it could be the coil or the pickup I replaced them and still have the same problem. I did just find a connection unplugged, on the under side of the plenum next to the pressure regulator boy that was hard to plug back in!

O here are all my casting #
