I have a 90' 240. It will crank and run just fine. After driving it for about 35 to 40 min. It will start bogging out. If you let it sit for like five minutes it will start up and run for another cycle. Any ideas. And while looking through the wiring on it the other day. I found where somone has shoved a fuse into what looks like where a relay should be. I will try to get a picture of it tomorrow when the sun is up.
