X2. Start by checking for...
Fuel (is your engine starved for gasoline?)
Air (air filter plugged, is anything blocking your fresh air intake?)
Fire (ignition components failing?)
Fuel system is your most likely culprit. Don't overlook something obvious like a loose or disconnected accelerator peddle. You don't tell us if it runs fine at idle or not, if it misfires or if it's not running at all. I have to ask... How full is your fuel tank?
I have no idea if you have an electric in-tank or inline fuel pump or if your engine is carburated or fuel injected but I'd suspect it's too new to be old school. Good luck.
