Just to clarify, did you replace these parts to address this issue or has it started doing this after you replaced these parts?
Also, does the system start working again after you shut the engine off or at what point does it start working again?
Last. can you try to rent a gauge set from a parts store that as a tool rental program and check the pressures when this shuts off? Basically we are looking to see what the pressure is while it is running and then just before it shuts off. This may require a little patients to sit and watch what it does. I would suggest having a note pad and just record the pressures when they are changing.
