This will not be something you will have much luck finding. The compressor has an RPM sensor that the control head monitors. If the compressor stops or slows down for any reason, the control head will shut the system off. Very difficult to determine what caused it.

is the compressor shot? the rpms do slow down when the compressor is engaged.
