Hey guys i'm having a problem with my 98 vw jetta I replaced my fuel pump, replaced ignition coil and module, and fuel pump relay. Car runs for about a half hour then dies. It looses voltage to fuel pump and I get no spark from coil. I had a diagnostic done and it showed 11 codes but no major codes to keep the car from not running. Car runs for a half hour then dies I have to wait an hour before car will run again, in the meantime no spark from coil and no voltage to fuel pump. Some people say it might be ecu on the way out if anyone has ever encountered or has any insight about my problem help me out please.
