I was brush hogging my back field and the engine started to lose power and RPM. I limped back to the house and looked at the air filter, it was clean. Looked at the fuel filter and it looked dirty. When the new filter came in 2 days latter I pulled the old fuel filter and it was very very dirty with some water in the bowl. I replaced it with the new one. The diagram shows a spring that is at the bottom of the filter bowl but mine did not have one in there. I double checked. Started back up and it seemed to run fine. Ran the brush hog for about 20 minutes and it started to loose power again. What should I be looking at next? If I stop the RPMs come back up but just can't keep the RPMs up under load. It does seem to run a little ruff at low idle. Temps are normal. Trans fluid level is normal. I am not a diesel mechanic so I am at a loss.
