Wondering why everything on dash is stuck and lights are off

What is your question?

Driving home tonight and the dash went dark. Shined my flashlight and everything was stuck. Got home, turned off car and now it won't turn back on. Prior to this, I would drive and everything on dash would drop to zero, including mpg while driving. This would last a few seconds and then "click" back on. Everything else in car works, headlights, interior lights, windshield wipers, ect
