2000 Traxter shuts down
 

Hi. I'm new to this so bear with me. My 2000 Traxter 500 runs for 15 sec. to 2 mins then shuts down, just before it shuts down the display lights on the dash go off. Usually if the machine stalled the oil light would remain on. Is it possible a sensor is telling the mpem to shut down? All fuses are good ,spark is good, fuel to carb is good. I've replaced the mpem with the same result. Sometimes when I turn on the ignition ,the display on the dash flickers like crazy then stabilizes .When its idling the motor sounds normal.
Hope somebody out there can help as the machine is in really good condition other than this super aggravating situation.
