Hi Bill,
What kind of compressor is this?
If it's an electrical - please check the electro motor, the wiring and the main contactors.
It sounds like a problem with one of the phases - either in the contactor, the wiring, or one of the windings in the electro motor.
Good luck! Let me know what you find
