FWIW, when I had that problem, it turned out to be the little ground wire for the solenoid.  The quick connect was trapped on the tab, would not pull off easily, but was very slightly loose.  Vibration, heat and the ever-present oil film would let it open up for just a fraction of a second, then connect again.  

Replacing the quick connect and cleaning up the brown corrosion on the tab solved the problem.

I have also had a lockout switch that would do the same thing.  Removing the shim washer got it working again.  But I doubt you have those on your race car.
