Dixie Chopper Yanmar Diesel dies

I need some assistance with my YANMAR Diesel Dixie Chopper. It’s a XWD3500 with a 60” deck. It’s approximately 13 years old with 661 hours on the original engine. I’m the original owner. Problem - It cranks and starts up immediately (no issue), but after 30-45 minutes of being on with blades engaged it just shuts down - just like turning off the ignition//no smoke. It will start up again, but after 2-3 minutes shuts down again. I let it set for 30-45 minutes then cranks up again and won’t shut down again for another 30-45 minutes then shuts down again. I’ve replaced the fuel pump, fuel filter, drained water separator, drained both fuel tanks to no avail. Guidance is much appreciated.

Have you checked air filter? Post model & serial numbers from engine data plate. Air or water cooled engine, thanks Mark
See Troubleshooting Guide above. "Engine overheating" may be problem after reading symptoms you posted.
Looks like your engine is water cooled, impeller loose & slipping on water pump shaft & bearings may be on their way out. Water Pump may be a recall item, I would call Dixie Chopper with all Engine Information. Replace thermostat every time you replace a water pump. Being 10 yrs. old I would use new antifreeze. Let us know how it goes, thanks Mark

Might look at a possible safety switch shutting you down - if it is doing the same thing after you worked on the fuel system - either you still have a fuel delivery issue or a safety switch is shorting out - I think if it was fuel you would see and notice a bad running machine before falling on it's face, Being it suddenly quits it would make me look at safety switch or your fuel shutoff circuit.

Does it have a fuel shut off solenoid.?
If so wondering if that could be acting up for you..
Not sure if they fail open or closed though..

I am going to look at all areas you all provided. Water pump, fuel solenoid, fuel shut off switch, air filter etc. these are areas I did not look at. This is Ralph my number if you have any questions 361-255-0099

Fuel shut off solenoid has two circuits one to pull it in and one to hold it in. Been a long time had one that the hold in circuit wiring had a bad connection.

When you turn the key to start the pull in circuit pulls the solenoid and opens the valve. When you turn the key back to the run position the hold in circuit kicks in and holds in open while it is running.

I pulled the air filter out and replaced it with the same OEM (Donaldson PN 181050). It was not clogged up but it was dirty.

I also found the temperature sensor on the thermostat housing “terminal” had some play - looks like it was over tightened and terminal may have broken inside. It has one wire terminal connected to the stud, which is tightened, but the terminal lug on the housing has some play. I don’t know the part number. The gauge indicator on the mower panel reads from 0-280 degrees (f).

I have a xxwd500072 48 horsepower yanmar with turbo diesel. I have had similar problems with mine. It is one of two issues.
Firstly, there is a small filter that in my opinion that should not be on the mower. If you raise the seat, you will see a SMALL inline filter not far from the fuel pump. Secondly, I have replaced the diesel shutoff switch about 4 times since 2005.
There is not much that can go wrong with a diesel. Hope this helps.

Wow. Thanks for your input. I just changed the inline fuel filter (just before the fuel pump) yesterday Oct 15, 2023. I have checked everything else and figured this could be the culprit.

Question- where is the fuel shutoff switch. I have not checked/replaced it. ???

Where is the fuel shut off switch? Can someone show me location and/or a photo of it? I would really appreciate it. Thanks

Inspect fuel tanks for dirt & debris. Pick up a small bottle of Diesel Fuel Treatment & follow directions on bottle before adding to fuel tank.

I wanted to close the loop on my forum question. A BIG THANKS to all who provide recommendations to my Dixie Chopper problem.

After replacing the in-line fuel filter pre fuel pump I was able to get a full 1 acre cut without having my Dixie Chopper shutting down. I will cut my 1 acre again this coming week and see if it holds up. Again-Thanks forum Brothers.
