On the bright side it's not the pressure switch or programming. We had an issue where it would turn off the compressor 9 times out of 10, but that one time it would keep going. Even after changing out the switch and all the wiring. It sort of just fixed itself by competition... Anyway, check if it's in a relay port with the right polarity, and if not, switch it. If you replaced the spike, the only things left I can think of are the digital ribbon cable, sidecar, and the cRIO. I highly doubt it's the cRIO, but these things have ghosts in them.
