Occasionally it'll idle down less than half of what it should idle at. I shut it down and check the fuel filters and no fuel in them. I take them off, and put back together, fire it up and it'll be fine for a few weeks then do it again. It's only shut off on me once due to summer heat. I want to get this fixed (warranty is up this fall)I don't know if it sounds like a warranty issue, or some simple mods I can do myself. Seems it's starving of fuel. Any ideas of what this could be? I appreciate the help!
