You could very well have a blown head gasket.A simple cylinder leakdown test will find the problem.If your motor is under 2 years old it will be covered under Kohler's warranty.Good luck :)

Also, Check the top RPM's they may have dropped below the 3750RPM's(no load) and now dropping below 3500 RPM's under load
