Please Help, in the dark, tail lights, brake lights, dash lights, cut out

Started up truck, Driving,

Dash lights cut off (except gauges)
Clock Reset (truck did not cut off)
All tail lights cut off, including roof
Brake lights not working.
Left blinker flashes 5 times then cuts off, every time between blinks mileage light cuts out, like the blinker.

All at the same time. Check fuses under hood and under dash, both fuses for the tail lights blown, replaced them, worked for about 4 pumps of the brakes, then cut off again, fuses blown.

Everything I can find says break light switch, but would that make my dash lights and tail lights go out too?

 

If you have a trailer tow package, check your convertor box ,it's the box that your trailer light plug comes out of these thing can cause electrical problems if they fail.
