The X530 starts fine and runs well for about 45 minutes and then starts running rough. Sometimes it comes and goes, but today I mowed two lawns and it did it both times. New plugs, oil changed, and air filter. I added a little Seafood and have been running the ethanol free gas. Any ideas or thoughts as to what is going on?
Thank you

I had an older Kohler command do that,,it ended up being the coils,,when they got hot they developed high resistance in a wire and it would start to cough,hiccup and act up.
Might even want to check valve lash.
Buy an inline spark tester and run the mower with it in place.
When the engine starts playing up have a quick look at the tester.
If it is also flashing inconsistantly then you have an electrical problem and most likely the coil as previously mentioned .
As these are expensive little buggers it is worthwile checking before you buy a new one as you can not take it back for a refund.
