Had this issue on mine when it was new. I would have plenty of PSI until I hit 50 then it would drop way off.

I had a clogged poppit valve, it wouldnt hardly get to 10 PSI.

I have also noticed as the water temps have gotten warmer, my pressure has fallen. Was getting 25-30 in the winter, now 15-20.
