Atwood furnace blowing cold some time at night...

I have an Atwood 7900 series furnace in my 2001 Lance 915. DSI iginition, no external timer relay. The past couple nights I have woke up to cold to find the heat has shut off and it just blows cold...

I was lucky and was there during a failed relight. It tried three times, then just ran the fan.

So I'm guessing it could be the board, ignitor itself, or the gas valve limiting flow? Now what the hell do I do? I'm guessing for the price of paying someone to diagnose it, I can replace all three and have peace of mind?

Thoughts?
