I have a 1994 Grand Cherokee Laredo, 4.0 engine, straight 6 with 140,000 miles. The engine will shut off while driving after 15 minutes or so. It will start again after sitting 3 to 5 minutes but will again shut down if driving another 20 minutes or so. We have checked the crankshaft sensor, the idle control sensor and the computer board, but all tested out according to troubleshooting codes. Anyone have any ideas what this could be. I'm afraid one of these times it will not start and leave me sit. Thanks.
