That aligns with the Owners manual and would constitute and out of gas condition; which would require Priming to refuel. It could also suggest Operator error, or more like misuse if in fact the priming was required because gas has evaporated. Onan has a clear procedure in manual if the genset is NOT going to be used for lengthy periods or placed in storage.
With that said; keep in mind that the OP says...
It currently has 42 hours on it. I changed the oil and air filter at 25-hours, as per the owner's manual. The rest has been running it for 20-30 minutes under load every month or so, just to exercise it.
Which goes to my argument #2 with Generators that I will never understand and that is WHY do people seem to NOT want to use them but once every blue moon or as little as possible?; and then complain that they are not worth a crap (pun intended) because they never seem to start when they need them?
I would love to see an accurate log with graph of the exact start and stop times along with duration in secs for each start? I average 6 - 7 hrs / month, but my guess is that it prolly should be at least 2 hours per month with full loads with each start being a min of 10 minutes.
