Simply Build It

it could be a few things, are the radiators getting too hot ? it could be over heating or it could be a faulty over heat stat.

Not familiar with the boiler, but does the burner/pilot light then go out ? could be a problem with the flame sensing electrode.

Or if it doesn't light, it could be a fault with the ignition, either the lead, spark generator or PCB
