yes, except mine would not trip the breaker in the box. I think there
must be an internal thing in pump because it kind of locks up. And I
have to unplug it and let it cool off I guess. then plug it back in and
its good. but i found that when this started it was time to clean the
pump and pipes. Pump probably overworked. In fact mine is a foundation
drain sump pump and the blades and pipe all were coated with 1/2" of
sediment...

The pump overheats due to air lock (from sediment buildup?) then
stops pumping. Imagine an automotive fuel tank with no air
inlet. In this case the car stalls and the fuel tank collapses.

I'm not sure this is your problem.
