Good point GX150 made about checking the fuel cap for venting. Not sure of the crossfire but the ASW buggies have an issue with the ethanol in fuel reacting with the plastic of the fuel cap. On several ASW buggies and just a handfull of Kinroads the fuel caps due to the ethanol content seemed to melt the insides if the cap blocking off any ventilation of the fuel tank.If totally blocked you will run until engine runs out of fuel then after 5 minutes or so it will start again and run, but if restricted it will act as if it is running out of fuel at high speeds but run fine at idle and lower throttle speeds. It blocks it enough slowing the rate of fuel.
