I have a Maytag Drop in 30 inch range. If I use the four top burners at medium or higher settings and have the oven on, the entire unit totaly will randomly shut down for 30 to 40 minutes, then it will power back up and the clock start blinking. What could the problem be?

The problem is you are drawing too much current having all hotplates and oven on at the same time. Where I come from this would trip the circuit breaker and you would have to reset it manually. The circuit is normally rated about 32 amps.I haven't heard one of these resetting itself. Anyway, normally you should only be able to have 3 to 4 elements working at the one time. Any more and it will trip.
