No, not time to knock on wood
You have two questions
1) Why does this only occur when you are almost out of gas?
my guess .... less gas in the tank means more empty space and vacuum,
also less weight of gas to push it down.
2) Why does stopping in the middle help?
The vent cap is probably not completely blocked so stopping allows
the tank to vent. Also may allow the gas tank to warm up in the sun.
So you have two solutions
1) fix, or buy a new gas cap, personally, I'd attempt to fix it,
worst thing that could happen is you have to buy another, although
check price before, this might be costly
2) stop occasionally and open tank

Subject: Re: [Virago] Did it again!! Out of gas!
if opening the gas cap helped you'd think the vented cap wasn't
functioning
right, but why it would only do it when almost out of juice doesn't
follow,
well maybe the tank/cap is more "susceptible" to pressure build up
when
there is mostly air vs. gas.
I'm thinking back on the length of time running. The first time was
116
miles straight when it 'ran out'. The next tank was 142 miles with
several
stops and starts and she did fine. The next tank was 113 miles with
one stop
midway and I'm down. Is it time to knock on something with a
screwdriver or
replace a gasket?
I know you like to take your kids exploring, Jeff so if you're ever
in the
Texas hill country, check out Enchanted Rock. There's more history
there
than I've had time to research and still don't know if I could make
it to
the top! I'm thinking MY tank would suffer an air lock as my old
legs hauled
my arse up it.
