 Hesitant to ask this but have you checked the voltage drop at the rotator? 
Might or might not be the problem. It could be you simply need a low 
temperature grease instead of the stuff that turns to a rock. Try something 
synthetic?

 Make sure there's >12VDC at the rotor.

I have found that when all electrical issues seems OK, that it's time to look 
at degreasing the thrust bearing, then loading it with new grease. Also look to 
lubing any other areas where the mast might be metal-to-metal contact with 
other surfaces.
