I have seen this cause the problem. Although the fully synthetic oil does provide proper lube for the engine, by the time the low oil switch sees the pressure it doesn't like it and errs on the side of caution. I have had to do more than a few oil changes to prove this to boat owners that were trying to get better fuel economy out of their marine gensets. Easy enough to see if this may be your problem. Also a different low oil switch make like what it sees better than the one that is on it now.
