Got Gas???

[GiantONAbike]

OK so here is the deal. I got this bike and was super stoked (excited, so cal talk sorry). Anyway i was riding when all of a sudden the bike shuts off, I try to restart is and it turns over and wants to start but seems like its getting no fuel. So i look into the tank and there is half a tank of gas in there. So i fill it up took maybe a gallon and a half and started up with no hesitation. Once again at about the same gallonage the bike shits off and a full tank she runs. Any suggestions on this? Its really annoying. I checked all the fuel hoses and non are pinched or kinked in any way. The motor is burning oil worse than my old v8 muscle car, so i know the bike need tunning!

Thanks, Mark
