Greetings, hoping someone out there can help me out. I have a JD 445 with a 22 Kawasaki EFI. First time I've had this issue, once it runs for 20-30 min the engine begins to sputter, it won't die, even with PTO engaged, but gets close. If I shut down the motor, wait 5-10 seconds, it will run fine again for 15-20 minute before the problem returns. So far I've changed the plugs, coils and caps and fuel filter. I've seen other posts that this may be a fuel pressure regulator issue or possibly the MAP sensor, any help is appreciated!
