I had a case the one time that was driving me crazy. Outlet reads fine on
the testers, but would not run appliance. Finally the gal said she saw it
sparking "up there" and I tightened all the neutrals. Problem solved.

hey stumped I think you reached that destination already, no need to drive.

Sparking "up where" in the sky? That's lightning - coming to get you.
