It’s not just the ethanol, but if the tank isn’t full, there’s always condensation in the inside of the tank that forms, so that’s a second source of water right there. That’s one that can be avoided by a full tank though.
It was totally full when it stopped running.
Luckily, Himself is a motorhead and after ripping everything apart, he found the water issue.
Lots of gas treatment got poured in and after he got the gas lines thawed out, it ran again.
[I keep telling him to *not* keep buying the ‘great deal’ gas at the VA state line truck stop]
