My D1 has 305k Miles also has intermittent ignition cut out, with a code P0102, cleaned MAF correctly, checked wiring and vacuum leaks looks ok, also read in the posts that VSS could produce this symptom while driving. I replaced the sensor however problem still there. I also read that faulty fuel pump relay is a pontential. Test drive showed no recurring codes however left stopped for two hours went to re start and noticed black smoke then stall and hesitation then smoothed out. Ran well for another hour then stopped went restart idled and then shut off. Going to try relays never been changed see if it’s that simple! Any ideas are always appreciated!Boxster
