I have a 96 Jeep Grand Cherokee Limited with a 4.0 litre six cylinder and 4x4 transmission. It has died on me several times while driving but was only a fuse on the passenger side under the hood. It was located in the section that says TRANS. When I replaced the fuse it started right up.
Check the oxygen sensor. My 1995 Grand Cherokee stopped stalling while driving after it was replaced.
