Im starting to think it is the pressure switch but not sure and dont want to tear into it before i have a better idea of how or what might be the actual trouble.

Hi Jim, does that air line connect, to an electrical box? You may have sticking contacts? Or the air cylinder inside is sticking. You should have a power cord going into the pressure switch electrical box, then wires or cord, going to the motor. Clear as mud? Google 220 volt air compressor wiring. Hope this helps!
