This is just a guess when it happens install a pressure gauge in lift line or steer cylinder and see if you have no pressure it is possible the hyd pump shaft is worn or the gear inside the motor and it slips at times if no pressure pull pump and check spline it is splined to the motor gear. Hope this helps.

Fact of the week
Some trees retain a form of biological memory of past droughts, and after surviving a dry period can change how their stomata (tiny pores on leaves) regulate water, and adjust growth patterns for years afterward.
