QS 933 shuts down/restarts after couple of hours?

[freescotland]

no dust bunnies, I will R&R, good idea.

I only gave a quick check on the fan, but need to let it heat up a bit I suppose and see how long it runs. I guess having the side open though, it will be pretty cool, so if it still restarts, that will rule out heat.

thanks for all the advice
