2019 bx2380 starts and runs great for about an hour. Then falls flat on its face, it doesnt quit running it sputters and rpms drop for a bit. Returns to proper rpms and works great for 10 mins then does the same thing. If i shut it down for a couple hours and then start using it again it works great for another hour then the same process starts all over. WTF??? Anyone know whats causing this.

I'm having the same issue with mine (m100). Try cleaning your water seperator out. Check for fuel filter, fuel lines. But most importantly, check your fuel. Any water in your fuel with wreak havoc on your lines and supply pump. Right now my machine is tarped with a heater under it. Give that a try and I hope it works for you.

Yes, sounds like fuel starvation. MIght have goobers floating in the tanks. Perhaps a glob of algae? After a while it gets sucked to the intake and chokes the fuel supply. Or a leaf or similar object.

What others have said - the fuel is being restricted. Climb under and look at the first filter - see if that looks "dirty" - but based on what you are saying the tank is the problem.

On the older models it seems that the fuel sending unit breaks down inside the tank and the little pieces float around and then finally get into the small fuel line leaving the tank. When the pump is cut off it floats around a bit until it sucked back. Or it could be anything in the fuel system - Like Ikc1990 said - a small leaf will drive you crazy.

One way to check............

Run your tractor first with the tank lid unscrewed a bit .......... you could have a clogged air vent on the cap causing a the pump to fight a vapor lock

If it still stalls....

Next pull off fuel line at filter 1 or at pump - have a large container and see how fast it comes out, should be a steady stream...... but if it starts to slow down (assuming tank near full) then you have found the problem.

Taking the tank off if you find that to be the case - is not a fun process - but doable.

i think you all are right. I have always thought it was a fuel problem. I think i am going to install a fuel filter with water seperator. This model has 2 inline filters no water separator. Also going to go ahead and clean fuel system🤬🤬. I will let you all know how it turns out. Thank you!!

I think you are on the right track. Also consider where you are buying your fuel, and if it is likely to be a high turnover place that provides clean fuel.

I had a bad experience buying off road from a place nearby years ago. It clogged the fuel filter on my B2910. Was really strange, as the tractor was only months old. Decided to change the fuel filter on a whim, before having the dealer pick it up. The filter was blocked solid, could not blow air through it with my mouth. BUT the tractor ran fine for a while, then about died, recovered for a while, then repeat.

Only mentioning this because it still amazes me, and causes me to think your issue may be related to clogged filters, and that perhaps you might want to consider a different source for your fuel. I ended up just using on road since off road was a distance for me and not cost effective to buy when time and gas cost was figured in.

I had a similar issue with my BX2660 a couple of years back. It was cold out and I used Diesel 911. It came out of it. I now use a different fuel supplier.
