Mower has history of stalling out about 5 to 7 hours into the cutting day. We are a small lawn care operator servicing mostly residential properties. The problem occurs when the mower is in operation with cutting deck engaged. Mower will restart after allowing it to sit for 15 to 20 minutes. Three trips to two different dealers for diagnosis and repair. Mower is under warranty and only has 126 hours. No EFI problems (no codes) detected with computer diagnostic equipment. Two trips have resulted in technicians finding debris (a pine needle, grass) in gas tank. Both times they flushed the fuel system and cleaned the gas tank inside. The best guess is that when the mower gets hot the debris is adhering to the gas tank's internal fuel filter and starving the engine of fuel. A cool down may be allowing the debris to fall off of the fuel filter (fine screen) and then the engine can restart. They cannot explain how the debris is getting into the gas tank. They have replaced the gas cap and had to replace the fuel gauge since it stopped working (stuck at 1/4 full). This mower serial number is H9500265. Anybody else experiencing this type of problem?

Have you found a solution to this yet? We had the same issue on this model, replacing the fuel filter solved the problem
