Walker mower 26 hp efi stalling out

I have a walker mower with kohler 26 hp efi in it ran good then last week it started to stall out but not completely then comes back and tries to stall out again. So far ive changed the plugs, fuel lines fuel filter, checked gas cap. I ran the code on the motor and it shows no code errors any ideas what it may be??

Is it worse at full throttle? Have you checked the air filter?

I see a relay attached right near the computer.Its cube shaped with 5 prongs. It measures about 1.5" square.Is that the one?

In the parts manual that came with my Walker years ago,for the part number,it has "NS" . For description,it simply says"Relay(Kohler)"

Was your mower missing? Is that why you changed the relay?

Tock,did you mower start acting like this in the really hot weather or does it do it even in cooler temps? What year is your machine and how many hours?
