Started up fine as usual in the garage run it about 2 minutes prior to pulling out...rode about 2 miles slowing down for a red light on a bit of a down grade and about 50 feet from the light..."POP"....ENGINE QUITS. Good thing I was on a down grade to the intersection, coasted around the corner and having enough speed going to pull over to the right about 50 feet from the intersection. Needless to say, traffic and all of a sudden no engine. Have no idea what caused that, I use good gas, been running everyday and this never happened before. Pulled the emergency brake on, waited a few seconds, turned the throttle slightly and hit the starter and it started like nothing ever happened. Needless to say the "Pop", like a big balloon bursting, scared the hell out of me. Is there something I should get checked???
