Hello Paul , my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. In order to help you determine the cause the first thing that you need to do is install your pressure gauges and read the system pressure when the compressor is running. Check this for me and post back with your reading and I will help you determine the cause.
