Dash display going in and out while driving?

What is your question?

Engine will still be running while this is happening. All needles on the dash will fall completely to the left and all lights will come on at the bottom of the dash. The transmission will remain in the same gear while this failure is happening, No downshifting or upshifting. The car will not crank if it is shut off while this failure is happening, but it will crank and run fine once you let it set for about an hour. ANY SUGGESTIONS?
