If you have no power anywhere, I'd start with the basics - put a meter on your battery and make sure you have power (yes I know you ran it just a while ago but I have seen batteries develop an open while driving and be absolutely dead..happened to a co worker with their Pontiac a couple years ago).

above first, follow 12v downstream until voltage is lost. Be sure to check grounds and inspect for dark, loose or corroded connections.
