Could be a simple 'flame failure fault' - lazy gas valve, faulty ignition/flame sensing electrode etc etc
But could also be a flue fault, if there's a break in the flue the combustion gases mix with the return air within the flue - the flames will start to search for oxygen and lift off the burner/electrode.
RGI needed
