Kubota BX23 Caterpillar 416
I've had a recurring problem on a 2003 BX23 with about 400 hours on it where the engine will go into this mode where it runs very rough, and barely idle regardless of the throttle setting. Sometimes it will die but will usually start again and run rough. Eventually it will clear-up and run fine until the next time. When this first occurred a couple of years ago I changed the fuel filter but that did not fix the problem. Recently I realized there is a 2nd fuel filter but have not changed it yet. The problem does not seem to occur when the fuel tank is full. That makes me think that it may be a weak fuel pump and because the fuel tank is close to level with the engine, a full tank is able to push fuel to the engine.

Has anyone else experienced a similar problem or have any thoughts as to the cause?

Thanks,
Chance

Thank you for the link, that definitely seems like a possibility. I'll look into it.
