got a question, I have honda 2113 tractor. about 5 years old. last year started having a problem. Starts fine, runs fine but after 45 minutes or so, suddenly dies and won't start again until its cooled off. later that day, starts fine and does the same thing. seems like the hotter the weather, the faster it would die. could this be an ignition problem? Thanks for any suggestions!
