Does anyone have a loss of power issue. After tractor warms up 10-15 minutes tractor loses power even if pto isnt in use. No error code. Runs perfectly fine cold full power and acceleration up my hilly property even running an implement. Then if implement or not if trying to move , work, or even accelerate rpms drop down and will stall unless I let off pedal and then rpms will recover but any attempt to move causes loss of rpm back to stall levels unless I let off the throttle pedal.
