The first time was while driving, it seemed like it started to miss and lose power for just a few seconds. The second time later that day, When I started it it ran smooth for just a second or two. Then, well the best description is it started to diesel or miss and I couldn't get the RPMs up when I gave it a little fuel. After letting it sit for about five minutes it started up and ran just fine until I got home. I shut it off and started it again and it started to diesel and died. Any ideas? I have checked oil level, batteries,fuel filter, drained fuel canister for water, the fuel pump seems to be working, but I don't have a way to check fuel pressure. I did find a burnt wire to the glow plug and replaced the wires and valve cover gasket. Still nothing.
