Compressor shuts off within 5 minutes with cold start up, then runs fine?

Hi there.

What would I look for to fix a geothermal compressor that shuts off within 5 minutes of initial start up from cold, every time, then after a 10 minute wait will start up and run fine for hours. High Pressure and Loss Of Coolant signals are good going to control board, nothing much else going into control board. I suspect the compressor's own thermal shutoff, if so what is a course of action? Compressor discharge temp stays around 195 F. This is a new old stock system that is 8 years old and just getting used for the first time. Thanks.
