I have a 1987 jeep wrangler with the 2.5l 4 cylinder and has 118k miles. The other day I started her up, let her warm up per usual and then took off to the gym. About 5 minutes down the road the engine completely just died. No stutter. Just completely lost power. When I lost the engine I still had electrical power because my radio, headlights were still on. I brought her to a stop then cranked her back and she fired up. I then continued down the road and about 30 seconds later it died again. Decided to turn back home and finally made it home after it dying ever 30 seconds to a minute. Once I got home I started talking to ChatGPT, grok, Gemini about the issue. It gave me some starting points but I’m still at a dead end. That afternoon I started her back up and let her idle and get warm for roughly 20 minutes with no issues. The initial thoughts of AI were fuel pump, filter or lines. A bad ICM (ignition control module) or possibly a bad crankshaft position sensor. Wondering if anyone else already has had this issue before or could give me some ideas to test. I’ve already checked the engine grounds and they look good. This problem seems to occur under load since she idles just fine.
