When lifting bucket or tilting bucket solely the bucket hydraulics work fine. However, if we tilt AND raise/lower the bucket at the same time the hydraulics quit. Has happened twice. First time we let it sit for 2 weeks - tried it out and everything worked normally for months - but then got in a hurry and made the mistake of tilting and lifting the bucket at in the same motion and hydraulics died. Been dead since.

I'm thinking it could be a pressure valve problem - what do you all think?

Any ideas?

Thanks in advance for any help. We've checked the hydraulic fluid levels and quality - they appear normal.

Do any other hydraulics work? Steering or scv? I assume you have independent loader control valve? I would start by changing the hydraulic filter, draining hydraulic fluid and cleaning the screen. You also could have a bad stroke control valve in the pump. Answer back with more info and we'll see where to go next. ....
