Yes a very good point. I must engage brain properly before jumping to conclusions next time.
One possible problem that would cause cycling once the boiler has heated, is an incorrectly set gas valve, with too low a setting to sustain the flame when the boiler modulates down, or poorly adj flame sense probe.
Causing it to drop out, restart the ignition sequence, light, temp rises, modulates down, flames goes out... Etc
But would need checking by an RGI, as definitely not DIY territory.

Thanks. The MI states the latter of the two causes you quoted. There are two facts to specifically consider. The fault emerged suddenly (there was no gradual worsening or known event which caused it) and the first cycle i.e. when the boiler is cold, lasts longer than those following. I'm trying to eliminate anything outside the combustion chamber or involving gas first, before getting an RGI in if needed.
