PMX stalls

Yesterday I was balancing a single tube (C8) and then aligning with the finderscope. I just had the handbox controller plugged in (no computer so no error codes to report). Four times when I was in a certain position - OTA facing NW at about 50', I pressed the RA arrow and it stalled-
I originally thought it was a balance issue so I rebalanced again and again.
Then it occurred to me that this is how it behaved when the RA cable became loose- nope not that either, checked twice.
Then I checked all the slack in the cables and moved it all over it's arc with no snag.
I then thought it was the cam stops so I tightened those.
There was a single cable hanging off the scope so no other source for snag or motor obstruction.
What else could it be?
(This mount was performing flawlessly with much greater loads only two weeks ago)
I haven't updated the software till now (as it wasn't broke!) so nothing else changed)
Any thoughts?
Graham
