Boomer 37 randomly shuts down (not DPF)

ronaldbeal · Mar 30, 2026

I have a New Holland Boomer 37 with 280 hours on it. Once it warms up, it just shuts off.

No errors on dash, no codes. Once it cools off, it will run again parked, sometimes for 20-30 minutes, sometimes just 5 or 10. Have run it high and low throttle. seems to shut down faster if moving.

I think (but not %100 sure) electrical is shorting, and killing the fuel shutoff solenoid.

Any ideas on how to better diagnose this?

Might be a 'ground' problem. Or any of the heat sensing sensors. pull them one by one and clean contact points and re-install with CLEAN threads! Especially if the sensor body acts as a ground to block or whatever (one wire)
And check looms near pinch points and HOT surfaces. Does it have a fuse block that's full of crud? I took a pic of mine and then pulled all the fuses and blew it out and sprayed a lube foam in each position. Then wire brushed each fuse contact 'legs' and re installed according to pic. (NOW I have dash lights!) Didn't help my fwd or reverse, but at least I cleaned checked.
