I've searched the engine shut down situation, but sounds like it can be a bunch of different problems. Thanks again.

I know 10 hours does not sound like much but it seems like most of this 10 hours would have been done last fall unless you plow snow with it. So many things can go wrong over a winter storage. Fuel can gum up tank, lines, filters, pump and carb as Sam was eluding to. Is it getting overly hot just before it shuts down? A rodent could have easily made a nice little home in your tins over the winter that wold cause overheating and all kinds of problems. I agree it most likely is a fuel problem but just wanted to make you aware that a 10 hour old rebuild does not keep problems like this from happening. Belts would not make this happen. If a pulley was stuck or a belt was causing that much friction the belt would burn up before it would stop the engine in most cases.
