2007 Bobcat 431G hydraulic issues, replaced plastic connector but now it deadheaded the pump and stalled motor when I was turning Right

[Blu-Ox]

Anyone have anything similar happen, It started right back up and I used it another 30 minutes or so hasn't happened again. When I changed the pump connector the metal gear was only in the plastic one about a 1/2 inch and it stripped the plastic gear, rest of it looked good but I replaced it with new gear and plastic coupler. before the coupler tore up a few times the machine kicked out of hydraulic power when i turned it or when i tracked then it finally stripped it out. I'm thinking maybe a relief somewhere isn't working or sticking, I'm not really sure but I think the pump is wining a little louder than i noticed before. the machine has all kinds of power so I really don't think it's the pump, Any suggestions would be appreciated
