The sander uses a capacitor start, continuous run, ac induction motor. These are the quiet motors you find on your larger table saws et al. so brushes shouldn’t be an issue here. But that did make me think of one other possibility.

We have a 10” Craftsman hybrid marble top table saw at work that had an issue with its motor about 6 months ago. Investigating the matter we found that a capacitor had at some point literally caught fire and had charred the inside of its cage and a bit of the connecting wires. Quite scary to see that after the fact; of course, Craftsman were like, ‘yeah and so what, what are we supposed to do about it’ but that’s a different matter.

Anyway, definitely check the capacitor cage on the motor. If the capacitor popped or caught fire, it would have definitely caused your machine to stall out with the reset button being extended out.
