It sounds like your engine may be experiencing overheating or fuel delivery issues after a few laps. Start by checking the cooling system for leaks or a malfunctioning thermostat, as overheating can lead to engine failure. Additionally, inspect the fuel system for clogs or a failing fuel pump, which might restrict fuel flow during extended use. Finally, ensure that the ignition system, including the spark plugs and wires, is in good condition to prevent misfires as the engine heats up.
