I have a 2009 Hustler Sport with less than 50 mowing hours. It will start and run about 10 and then dies. I cannot get it re-started. What could be the problem?

Hi,
If you mean 10 minutes, it is most likely a fuel problem. Try loodening th gas cap first to see if that is the problem. If not then suspect the fuel pump.
Would be nice to provide numbers like model and engine, especially engine since some models can come with different manufactutrers and model.
Peace,
Clarke
