I have a New Holland Boomer24 with only 115 hours on it. It is a 2014 model which I purchased new in late 2015. Last year it started missing and pulling down when I was mowing. I seemed to be able to mow for 45 minutes before this started. It pulls down, I turn off the PTO and in a bit it ramps back up. It may mow a couple of minutes before it happens again. The dealer said I needed a fuel filter. I purchased one, put it in and it ran great for about an hour. The next time I used it, the missing started after 30 minutes. It was at the end of the summer, so I didn't pursue the matter. I had to use it in the winter to move snow in my driveway. It ran fine. This summer I started out mowing and it ran fine. I was able to mow about 3 times when it started the missing again. It takes me about an hour to mow. I called the dealer and again they said fuel filter. The one I put in before didn't have 20 hours on it but I said ok. I purchased another filter and this time I drained what little fuel that was left in the tank and installed the new fuel filter. I put a couple gallons of diesel in and it ran perfect. I mowed for an hour and a half without issue. The next time I started it it was back to the same issue. Started missing and losing power after 45-60 minutes. The dealer has no clue as to what may be causing it. He will come get and return it for $150 plus whatever other charges there will be.
Has anyone experienced an issue like this or have any ideas as to what may be wrong?
