I've never heard of a vanagon gas gauge "going out" but I guess it
could. You might have a bad ground somewhere (of course you DO, but
where?) and you might have a clogged fuel filter or tank outlet, where
the car acts like it runs out of gas and, in case of the former,
clears up in the absence of fuel pressure (so it seems like the new
fuel you walked to did the trick) and the latter, where adding gas
helps wash off whatever flakes of rust and crud are covering your
outlet.

Just guessing.
