Case 9040B bogs down and kills engine when metering bucket

I have a Case 9040B that bogs down and kills the engine when the bucket function is activated. Sounds like the pumps are going into full stroke when the bucket is just getting metered. I checked pump2 pressure and the pressure rises up to system pressure when the bucket is getting metered in both direction, no load. I checked negative control pressure, checked out good at 380psi at both pumps. Checked pilot pressure, checked out good at 580psi. System pressure checked out good. The problem...
