Any one ever have Gen 2 not start at gas top off?

Topped off tank on my 08 after 30 minutes of riding at Lake Tahoe. I hit the start button five times, it starts then dies. I hold the start buttom and give it a little gas and it roars to life. Started fine every time we stopped on WB Hwy 50.

EFI? Elevation? I just turn 8,000 miles on her. Maybe some kind of air lock?

In 15 months of owning it starts in 2 seconds every time.

This was weird. Still a fun 331 mile weekend.
 
I've seen quite a few people mention problems with hot starts and loping idle after a hot start. Mine does it once in a while. I'm convinced its either the fuel in the tank, rail or pump getting hot causing a type of vapor-lock or a heat soaked sensor.

Pretty sure its a hot fuel/ vapor issue because it seems to clear up quickly after its running AND if I cycle the fuel pump twice before a hot start it tends not to happen.
