If it lights and cools, then goes out and relights after a restart, and it's worse at higher altitude, it's likely a weak flame signal. Thinner air means a smaller flame, and the board loses it. Check the electrode tip and position, clean the flue and baffle, and make sure the burner's clean. If those don't help, the board's flame sense circuit may be weak. The 618661 is in stock.
