problem with intermittent faults they have to do it in front of you,if it does do it try taking the combustion door off does it now run normally?it may hunt[flame table]but is it know behaving?if so you have either a blocked venturi or failing ap switch if not look at diverter valve,motor or ntc

do a thorough check of the aps silicone pipes for holes/splits/loose connections as this can cause these symptoms, it took me a while to trace on a glow worm recently.
