the boiler ignites for a few seconds and then switches off despite the fact that the thermostat is on full.

possibly a thermister problem, check resistance, replace if bad

or it may be the flame rectification probe is faulty, check leads, probe and pcb

or if boiler is kettling in a short space of time, it maybe the heat exchager needs replacing and system power flushing (sludge/scale)
