Rainbow E series Canister Wet/Dry Vacuum "tens unit shuts down" Questions

...unit rest for a couple days and tried it again, same thing. I would guess if the brushes do spin the motor must be OK. The motor shuts down and is not moving after 1 second, is it a circuit problem? ...

shuts off wait a few minutes and it will turn on but goes off again at ten (10) seconds????? These units have a automatic resetting thermal fuse near the motor to help to protect it from burning up by
