The car runs perfect, boosts fine then after its been running about 20-40 min, it will occasionally randomly stall, if you leave the clutch out, and turn the key off and back on the car will pick up and go again. I am thinking maybe the cam sensor? Any other ideas. There is no pattern to the stalling other than the fact that it always happens under load, never at idle and never in neutral. The car always restarts when you cycle the key, any help would be greatly appriciated.
