seems the boiler is cutting out &in again on it's overheat thermostat, if your pump has 3speeds move lever to pos. 3 ie move more water through boiler, or try turning boiler control down a little,
the setting limits the ultimate rad temp so will seem cooler but room will still get up to temp. even if a little bit slower.
if an old system may need flushing & new rust inhibiter adding,
