2011 Cascadia SERIOUS electrical problem URGENT help needed please!

I have had no problems with this truck since I took it to the dealer in Roanoke a month ago and had all the trouble codes fixed.

Tonight I stopped and turned it off...a few minutes later I went to start it back up...turn the key- nothing. None of the trucks systems are getting power. When I turn the ignition on the two side lights by the front wheels and two of the lights over the windshield, the two at either end, start flashing. No other lights flash, and nothing else happens. Ive checked every single fuse, in both blocks under the hood and the one is the glove box.

This doesn't make any sense to me. If it was the batteries, lights wouldn't start flashing randomly when i turn the ignition on. What in the the h3ll is going on here????

 

Checked that, all tight. Also tried turning the main battery switch off and back on it didn't do anything. Now that the sun is setting i can see that my dash illumination is flashing too.

 

I looked for cable fuses inside the battery box and didn't see any. I unplugged the batteries, gonna leave it like that overnight and hopefully resetting the computer solves this. The problem isn't a lack of voltage my batteries and alt are good and i drove about 9 hours today

 

Even when i turned the switch off and back on a few times that didn't help. Is there a way to bypass it?
