Gee, yours likely needed an oil change. Mine was coming up for one when I shut it down.
Yes!! It did. We kept praying that it would hang in there, and it did.
As soon as things were more back to normal (roads cleared, power on, etc.) we had it serviced.
We do before every hurricane season, but....that year...it had extra service.
Our area used to have a lot of power outages, in addition to storms/hurricanes, so it’s paid for itself...in reassurance, time and again.
