I had a komatsu pc200-5 that did that. Ended up finding a screen on that pilot control valve intake. There was trash that would plug the screen up after a few minutes of operation. If I let it sit overnight it apparently drifted off and would work again for a few minutes.

I'll give it a whirl. Can you change joysticks from one side to the other to rule out joystick being the problem? Does this happen under a certain situation or all the time? Does anyone think it could be the turret/swivel valve.

The screen was in the inlet port on joystickWas the screen at the leaver or was it from pump to manifold?? Thanks
