is that a problem because it's running out of gas??

Hi, everyone,

I am a new rider with a GZ250 (year2007, about 1k miles only, but I am the third owner). I ride it between work place and home, which is about 10 miles only. The speed I ride varies between 15-55mph.

Although I only ride about three weeks, I found a problem which happened three times on road:
In high speed (about 40-50mph) the bike got stalled (the engine got choked for a few seconds and then lose power): it feels like the bike is running out of gas.

After I pull off the road, I can't get it started right away. I have to wait for a while (about 20 or 30 seconds) then it can be started, and if I ride in a lower speed it's OK (I didn't ride for long to test it though), but if I reach to hight speed, it got stalled again.

This morning when I came to work it happened again. And I have to switch to the fuel reserve to get it started this time. Everytime after it happened, I went to a gas station to pump in some gas, then it runs OK.

It sounds like the bike is running out of the gas. But the strange thing is, everytime the maximum of gas I can put in the tank is around 2 gal, and as you know, the fuel capacity of this bike is about 3.4 gal, which means there is still more than 1 gal of gas in the tank when the bike lost power. And when I open the tank, it certainly has some gas still in it! It seems that there is something prevent the gas from flowing to the engine after consuming about 2 gal of gas.

Have anyone here had the similar experience? This bike has been sitted for about a year with very few ridings by the 2nd owner. May I ask your help about what is going on? Should I do some carb cleaning? Many Thanks.
