Vehicle: 1997 Subaru Impreza
Can you tell me what might cause the engine to cut out at highway speeds or die when at a stop light only after it has been running for approx 15 min?
Symtoms: Car starts fine and runs fine for approx 15 minutes. After 15 Min at highway speeds the engine cuts out or misses but then it goes back to normal and keeps going. It does this off and on when driving. When at a stop sign the engine will die but it can then be restarted. No errors lights are lit on the dashboard. Driver said issues started right after filling tank.
Troubleshooting: Nothing obvious under the hood like a vacuum leak or faulty wires. Checked fuel pressure and it was in range. Replaced the fuel filter. Plugs look good. Air filter is clean.
