I purchased a 2012 YTH22V46XLS and am happy with it in every respect excepting that after mowing half my one acre lawn it sputters and dies out. I thought it was just running out of gas and in each of the two times I've mowed the lawn I topped off the gas tank and it ran fine afterwards. The thing of it is that I only put a gallon or so in a three gallon tank so I am not running out of gas.
I replaced the spark plugs, fuel and air filters as well as the fuel pump after the first mowing with no change thereafter. Can I assume this is just a fuel cap venting issue or is there some other explanation?
