Problem w maytag dryer

Hello i am trying to figure out what parts i need for my dryer. I have been trying to research on line but not sure. Here is scenario: Gas dryer is igniting, i watched ignite and will burn gas for a minute or 2 and the shut down gas. From what i researched sounds like a radiant heat sensor or maybe thermostat and fuses. can any body give me a way to know for sure what problem is or should i just order these parts or any more. only pay shipping once right. thanks Chris

I would first make sure the dryer duct and fan housing inside the dryer is lint free. If that is ok and you still have problems I would suspect the coils on the gas valve are at fault and need to be replaced.
