I own a 2004 Great Dane Super Surfer. It usually runs great, and I haven't had any problems with it. However, recently the mower started having trouble. It runs fine, until I have been running it for awhile, and I am mowing on a decline, or when I turn, it will start to cut out. I will then kind of stop the mower, and then the engine will run again, until the next time I head down a decline or turn. Any help would be greatly appreciated. Thanks.
