I have a three year old LT 1045 with the Kohler 20 hp, It ran great the first year. Bought the little tune up kit and tuned it, drained gas, Maintained it in the winter. The next year ran great for about a month. started reving up and then almost dying, over and over until it began to backfire and stalled. would not restart until it cooled down. Thought maybe water in gas -no, unfortunately we had a drought that Year and I did not need it any more. This year I asked for help and got many suggestions, did them all. drained a cleaned the fuel system, replaced fuel filter, replaced all carburetor gaskets, replaced carburetor solenoid, replaced ignition and wire, replaced with new gaped plug, changed oil and filter. Ran great until it gets hot, about 1 hour then revs up and down and almost stalls over and over then begins to backfire and sputter and dies. It seems I spend more time working on than cutting with. About to stick an axe in it and leave it in the woods. Any suggestions?

Okay 86 views and no any ideas. I have come to the realization that the Kohler engine is a piece of garbage. I remember having one about 10 years ago and it was a piece of garbage. Got on it this morning ran perfect for 30 minutes then surges backfire etc... I could have bought 70 reel mowers for that much money and pulled then behind a 4 wheeler. Cub Cadet sucks!!!!

You say you replaced the ignition was that the switch or the coil? Have you adjusted the valves?

Did you clean the carb while you had it off?

Last time it was running good did you hit something like a rock or a stump or big ant hill that would put a shock on the engine

Ok first off Cub Cadets Don't suck and Kohler engines are not garbage. Next your list contains everything you've done except checking the exhaust system and arrestor, have you done that?

You probably have trash in your fuel tank and it is restricting fuel flow as the fuel line connects at the bottom of the tank.
I had the same problem and that's what it was on mine .

I have the exact same problem with this mower, mine was bought new in 2010 and worked great for the first year... when you start the mower it works great, after about 45 minutes when it heats up it starts to sputter and backfire. I have check the carb, filter etc... this is ridiculous that a mower this new is experiencing this strange problem. If anyone has any suggestions I would really appreciate it because at this point I just want to get ride of it.

I cannot understand for a million years why a new kohler would do this. My fathers cub cadet (late 60's) w/7 hp kohler worked great, this one is junk.

Have you checked for spark as soon as it dies?

Have you checked your valves?

Mine has over 600 hours.
Only thing I have done is deck belt and blades and oil and filter every 59 hours.

Have never touched the valves or spark plug
The mower or engine is not junk

No I haven't checked the valves, the motor/mower is new and only has 59 hours on it. What I don't understand is why it would do this after it has been run for 45 minutes. I would think it completely ridiculous to have to adjust the valves on something this new,

When you buy I new mower and read the book that comes with it. It tells you to have the valves done at 50 hours

My book shows the valves to be adjusted later than 50 hours. I would open the fuel cap next time it starts to sputter. That will get the fuel cap vent out of the way. Another I would do is pull the engine cover off the flywheel and check for debris under it. I would also check for debris in the fuel tank and flow out the fuel filter and bottom of fuel tank. Check that the carb is not loose on the engine.
