The only thing that will cut off heat to both the oven and the cooktop is if your oven is not getting 220 volts. It's apparently still getting 110 volts since the lights are working, but it's not getting 220 volts. The first thing to try is to flip the circuit breaker off for 60 seconds and back on. If that doesn't change anything the entire unit would need to be pulled out and the back sheet metal panel removed to access the junction block on the back of the oven. With a multimeter you need to test power between the 2 outside power wires coming from the power cord right were it connects to the junction block. If you have 220 volts between these 2 wires, then you need follow the wires behind the junction block because one of them is burnt or broken.
If you're not getting 220 volts to the junction block, then either your power cord has failed, or the outlet on the house, or possibly the circuit breaker on your house or the wiring in between. But you may need an electrician for these issues.
