On the rear of the main frame is a pressure relief valve that limits drive pressure to around 1800 PSI in the forward direction and to 50 or 100 PSI in reverse. I wonder if that forward pressure relief spring has broken. It is possible that the manual flow control (if it has one) has malfunctioned, or the priority valve after it has a problem, but I can’t offer specifics there as I have never seen it happen.
