Boost valve in the pump. Might've gotten some crud cycled back to the pump & caused the boost valve to stick. What's happening is your pump isn't cycling oil to the accumulator, it's just cycling oil in a complete circle back to your pan. You need to remove the pump & clean out the boost valve, or replace with upgrade boost valve kit. If it's not the boost valve, you might have a broken pump gear.
