I assume it is gas (having a burner) is it auto pilot or standing pilot? If standing the thermocouple or thermopile could be going bad and shutting the system down. If autopilot (spark-ignitor or glow) the flame sensor could be going bad .

Turn off the boiler, then remove the large tube going to the chimney. Check for any blockage....bricks which fell to the bottom, birds, squirrels, etc.
If the pilot is staying lit, then it isn't the thermocouple.
