I have a 96 XJ that dies at random when it warms up. It will run fine just idling forever, but as soon as it's driven it will sputter out and die. The engine is freshly rebuilt, and most of the sensors have been replaced. The Jeep runs great otherwise, and sometimes it will just run fine. Any insight, or people who've solved similar issues would be much appreciated. Manual transmission with the 4.0L engine, performance internals with slight cam. Just some useful information. Forgot to add, brand new fuel tank and fuel pump.
