My Milwaukee 5" random orbital sander just quit working mid job. It was spinning just fine and then sort of cut out, then came back on and finally cut out one last time before not spinning at all. It has a solid power source and the switch seems to be working just fine. Any clue what could cause this unit to randomly shit off?
