If the pilot goes out when it come up to temperature take it in under warranty and have them replace the thermostat! The pilot and burner lite flame are both controlled threw the thermostat. I've had bad ones right out of the box from the factory. Make sure they do a temperature check when they change the thermostat. That's were the oven is set to 350 degrees and allowed to stabilize and check with a calibrated oven gauge, should not be more than +- 50 degrees and yes the factory specification are within 50 degrees!
