My Ruud furnace blower motor runs and gas is ignited but after 3 seconds the burners go out. The blower still runs and it keeps trying to ignite and then goes out every minute or so

Sounds like a dirty flame sensor, on thenopposite side of the igniter there will be a metal rod, clean this rod with steel wool
