Possible faulty gas meter governor, as main gas lights the pilot may shrink. Simple test turn on any other gas appliance full eg cooker then turn on boiler when pilot lit and watch gas on burners on cooker if a visable shrink then is definately gas meter governor. Call Transco who will replace for free. Good luck.
