I thought it had to be a loose wire in one of the affected boxes which would make all those downstream also not work. So I took all the boxes loose one at a time and stripped back a little wire and reseated all the wires. So I know I have good contact in all the boxes. I even did the ones that were working and I took the GFI box loose and checked that those wires were making good contact.
Could a box be bad?
Could be just the neutral and/or ground wire of the romex going to the breaker in the breaker box, not the individual boxes. The neutrals and grounds all go to a common terminal inside the breaker box.
