2006 Honda reflex runs out of gas early

Yes, I did try the cap. Both times I did remove the cap to physically see the fuel level. The only remedy seemed to be adding fuel. I'm thinking that adding fuel was just a coincidence, cause it was not low on fuel and any cause of low level has been eliminated.
Recently I removed fuel down to the level when it last failed, bottled one gallon under the seat as a reserve. Rode the shit out of it till it ran dry. Found that you can add 3.2gal after running out, just as the specification sheet said.
Guessing that the electrical intermittan issue will be a continuing deal.

I wonder if the fuel pump isn't just a hair under the pressure that it's supposed to be. In this case, perhaps the extra weight/pressure of the fuel in the tank is giving it just enough to keep going, but when the volume gets low enough, it crosses over the minimum pressure threshold.

While I had the tank exposed, I ran the engine and removed the fuel line to the carb. With minimal fuel in the tank, the electric pump provided plenty of fuel to the carb to run the bike. I again am guessing the pump intermittently loses power and the float bowl runs dry. My multiple attempts to restart it must justle a bad connection or component into operating again.
I ride this scoot to work almost every day. It's only stopped 2 times, and these have been in the past 3 weeks.
The bike sits outside in the rain while I'm at work, if this continues I'll start running down the electrical wiring to try to find it. But for now it's 70mph cruise 20 miles one way every day. It's been a great ride for the last two years.
Bandito, great idea on that rear car tire. 20k and loads of tread left. Thanks!
