Have a 18 hp Kholer engine (model # CV492)on a 42" Craftsman lawn tractor
(7 years old). Problem is starts OK and runs for 20 minutes or so and then
starts to stall and lose power. Does restart but repeats problem. This
was the first mow of the season. Had run all gas out for winter. Used
fresh gas to start. Know I need a new battery as I can put a charger on
the current (orginal) battery and get mower started but should have
anything to do with the stalling? Changed oil and oil filter and air
filter. Have not changed gas filter or spark plug. Please advise, Thanks.

A failing coil or ignition module can act up when motor gets hot, see
if there is spark just after it dies.

I had a similar problem with an old (1969) Wheel Horse. There was dirt in the
gas line that would settle and then rise after the engine had run for while. It
would clog the float valve in the carburetor. Drain the tank and clean the
line.

Ditto - same problem & same fix. There was a screen filter at the end
of the fuel pickup tube in the fuel tank. Varnish sediment would be
picked up to the screen stopping the fuel flow. When the engine died
the sediment would settle back into the tank. Then recycle.

That does make sense. I was thinking more of smaller engines
I've serviced. Bad quality motor oil will cause problems.
Also, an ignition coil going bad. But, the crud in the fuel
tank makes sense.

Wonder if you can take the tank off. Leave about half full.
Plug the fuel outlet wtih a finger, shake the fuel around to
suspend any particles. Pour the fuel into a coffee filter
and strainer over a can of some kind. Strain all the
particles out. Put the now-clean fuel back in.
