Check if the oil temp does not reach 450F because if it does, it will trip the high limit device that will shut off the burner flame as well as the pilot flame. But if high limit device trips off prematurely (at temperature less than 450F) you have to replace it. Just make sure that its sensing bulb does not touch the fire tube.
