Angry Yamaha Generator Problem

I have a Yamaha 6600DE generator. The problem that I have is that sometimes when the generator is running at high speed, the low oil light will come on and try to shut down the unit. After a second it will then go off and return to normal. It is most noticable when a load is put on it after first starting but it will just do it randomly after running all day. Have changed the oil, serviced it higher and lower with no differance. Some days it is fine. Any ideas? Another person I talked to has the same problem. Thanks.

does this gen set have a filter? if so it is a pressure lube system. if not it may just be a dip and splash system and you could have something interfeering with the sensor, have you removed the sensor and checked that oil is in that passage?
also make sure that the gen is level when running. i have seen out of level surfaces cause this problem.
