Stepney 2,352 #2 Posted April 27, 2020 P218.. is that a 4-500 series tractor? Could be the ignition failing with heat. Be it the coil, pickup, or other. Try checking it for spark when it dies. I had a 516-h with an Onan that had electrical gremlins, and did the same as well as other odd things. My case it was just connections. Thats providing your not loosing fuel. Next time it dies hot, I'd check it for spark, then choke it and see if it gets fuel, IE wet plugs. 1 Share this post Link to post Share on other sites
