Engine Performance problem
2001 Mercedes Benz S500 V8 Two Wheel Drive Automatic 110000 miles
Motor runs fine for about 15 to 20 minutes and dies.
Check fuel pressure cero, but that wasn't power at the fuel pump, no spark and no inyector pulse. Car star again after another 15 to 20 minutes. I use obdII scanner to diagnose but no codes come out.
