Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

More likely the pilot is going out when the main burner shuts down due to turbulence caused by a clogged fresh air intake than a gas valve problem. If vacuuming the outside of the intake doesn't help the burner will have to be pulled and the intake under the burner vacuumed.

Not the problem, intake air clear
HVAC Technician: Rick, HVAC Supervisor replied 8 months ago

No way you can know that without pulling the burner and vacuuming inside. Since the pilot lights right back up this is by far the most likely culprit
