If it's blowing hot initially then shuts down you may have a fuel flow issue. Are you sure the tank is full? You could have a regulator going bad.
Try this. Light your stove top burner. You should have a nice blue flame. Now, while the stove top burner is on turn on the furnace and watch the flame on the burner. If it goes real low and/or burns yellow then I'd suspect there is a fuel pressure or flow issue. It may be a simple regulator replacement.
Do you have a switchover regulator and a dual tank setup? Again, make sure the tanks are full.
