Power steering on my L3650GST starts to fade (harder and harder to steer) after running for 2 to 3 hours.

Just noticed this happening this weekend. The loader wasn't attached but the 3pt hydraulics and the GST seem to work OK. This happened two days in a row. First thing in the morning the steering works fine. But after a few hours it starts to fade.

The hydraulic fluid level is OK. Could the hydraulic pump have an issue after the fluid gets warm? Any suggestions on what to check or test next to pin point the issue?
