    I have a Gravely zero turn with a 15 hp Kawasaki I bought used a month or so ago with 325 hours on it. The machine is clean well taken care of and runs like a champ...... until the other day I was using the mower and after about 20 minutes it sounded like it was starting to run out of gas and die. After doing that for a minute or so it completely died. I turned the choke up, turned the key and it fired right up and was fine for 5 minutes or so then the same thing. Im guessing its a carb/fuel problem but has anyone had this happen? Where should I start.

    Check fuel, check fuel filter, then fuel pump. If getting fuel past fuel pump, then maybe carb. Issue. Also make sure your still getting spark when this happens. But sounds like a fuel issue.

    Checked everyone thing...fuel filter, drained gas put in new gas, checked for flow on fuel pump, checked screens in tanks, switched tanks.....nothing. Then I was using the mower today and it started acting up again so I shut it off started it up again and for some reason decided to slow the throttle down a little bit ( about a quarter inch from all the way fast ) and it ran fine the rest of the time with no problems.

    I forgot to mention that it has been backfiring a lot too when I shut if off, almost every time unless I slow the throttle down a bit. Just a little FYI

    Sounds like it is running lean. Just for kicks try some sea foam in the tank.

    Wait, you don't idle it down before you shut it off? Like completely at idle?

    Not every single time like when I get in a rush and this is the only machine I have ever operated that has ever backfired on me.
