If it lights up then goes out right away then repeats this process you need to remove and clean the flame sensor rod off on the unit. The flame sensor rod is what detects the flame after lighting and tells the board to keep sending power to the gas valve to keep the flame going. Over time these get corroded and even go bad failing to send the correct Milliamp signal to the board. Normally a good cleaning with some sand paper will clean them right up and they will work fine again and in other instances they need to be replaced. The part is on the burner manifold and typically will only have 1 wire attached to it and will either be a straight metal rod with a porcelain base or a bent metal rod with a porcelain base. Get that out and clean it off then try it and see what happens. Here is an image of what you would be looking for to take out and clean off with sand paper. Note you may have to power the unit off at the breaker or wall switch then power it back on to clear the lockout.
