After probably having it on and off 30 or more times while setting it all up, it just lost all power again! No popped circuit breakers or anything.

Thanks for the warning. From the symptoms I would suspect a fractured rather than blown fuse. Slight heating from normal current and the fuse expands opening the fracture. Cool down and it works again.
