No electrical?

Lights all work fine in and out, but nothing happens when key is turned, wont start, no blinkers, radio, windows etc. I changed the ignition switch and nothing

I can open the door and have interior light, put the key in the ignition turn to accessory and dash lights come on as do the headlights. But as soon as I go to turn the key to start everything goes dark, not even a click from the starter, and won't come back on when key is cycled it has to sit for a bit before the lights will come back on inside. I'm not even remotely good at wiring. That's why I'm here asking for some guidance. Oh yeah and battery is new it has 12.7 volts at the terminals.

Vehicle listed above is an zr2.
