On the 1st after driving approx 25-30 miles , 2000 s80 T6 stalled and would not restart, cranked over fine. Acted like it was not getting any fuel. A good guy towed me into a parking lot. The next day,I walked back to it and it started right up. The same thing happened on the 10th, while for a tow truck , it started after waiting 90 minutes. Fuel filter was replaced last fall. Any ideas . TIA.
I don't have a repair manual (recommadations) . And where is my fuel pressure regulator at?
