Thanks in advance for any help. I have an Ariens walk-behind (model: A173K22) with a Kohler Courage XT-7 motor. It will start and run fine for about ten minutes, then it starts to sputter and dies. No fuel/carb issue, when I pull the spark plug, there's no spark. If it sits for about 10-15 minutes, it will start right up again (obviously there is spark again). Any ideas? Spark plug? Coil?
