I've got this F-450, 4 wheel drive, stick shift with a small (ha) problem.
From a cold start, (parked overnite) it's a little hard to start but runs normal until I get it 4 to 5 miles down the road (almost always the same spot), then the engine stalls for no apparent reason.
Wait a couple of minutes, do some hard cranking, and it will re-start like nothing's wrong and run all day without a hitch. Park it for an hour and it'll start right up and run normal, no problem.
Park it all day, then try to go home, the same problem comes up. It seems this problem only happens from a cold start. I'm worried this thing is going to strand me somewhere, and with ton of my tools in the back, I sure wouldn't want to leave it anywhere.
I've checked a few of the basic things (like the air filter and glow plugs) but I have to admit this prob. has me a little perplexed. Checked all of the electrical connections too.
I'd go to the dealer mechanic, but only as a last resort. His bills are always big.
Anybody have any idea what's wrong? Any help you guys can give would be great.
