Hi Paul, with you r statement above it is indicating it is something mechanical rather than an electrical problem unless you have a cable dragging or moving in this position.
Have you tried loosening the the clutches fully and then operating the drive through the full range. If it still stalls it may be a tight spot on the worm gear.
I don't see you have much to continue with other than trying to eliminate one thing at a time. next would be to mechanically disconnect the servo and drive it again without load. If the motor again stalls I am afraid you are looking at cables or electronics.
If it looks like being an electronic problem have a good look with a magnifying glass for a dry solder joint. Sometimes these will only show up when current is passed and the connection heats up a little.
Good luck.
