That's classic "bad thermocouple" behavior. It is also possible that blowing out the burner with compressed air pushed the thermocouple out of the place it is supposed to be. It might also have blown the tip off the thermocouple causing the "bad" response. (If so, it was almost dead anyway.)
I'd check the positioning of that thermocouple first, and if it is ok, then replace it. They are cheap and easy to replace.
The proper position will be such that the tip is actually IN the burner flame when the burner is lit, so that it can sense the flame. Of course, this causes it to eventually burn out, but in the meantime, it is a safety feature that shuts off the gas if the burner doesn't light.
