I have a garage with five radiant tube heaters with becket Oil Burners . Occassionally, three or four will go out on reset for no apparent reason. I checked the burners oil supplies, relays and nozzles, still cant find the problem. Could the differential air pressure switches cause this problem?

They could cause this . you could try and jump one out and see if it stays on check the hose connection to them Also check the flue is not blocked .
