why me

[Dean Romig]

Same thing happened to me with my '85 GMC. Lucky for me I was coming home from deer season in Vermont. Truck did the same thing to me at 9:30 at night at the top of the 5 mile grade into Franconia Notch. It was about 19 degrees with a 25 mph breeze from the North driving a snow squall with it. I had to sit there for about a half-hour after checking for spark and other stuff under the hood. Finally it started and I limped home, like you say, anywhere from 15 - 40 mph for the 150 mile ride home.
Turns out it was junk in the fuel that clogged my fuel filter and injection system and I discovered it came from the bottom of BOTH of my fuel tanks rusting on the bottom from water condensation that had just sat there for a while. It was a costly repair cleaning the fuel system and replacing both tanks.

Good Luck Charlie

Bummer Charlie. Fuel delivery or spark. You'll find the crud or the burned/cracked wire somewhere. So, why head home as the first option?
Cheers,

Make sure it also isn't a plugged up catalytic converter. I had the same thing happen on a return trip after fishing up in Canada with an 88' Blazer. We could drive for a number of miles, and would gradually lose power. After pulling over and letting it cool off for awhile, we could get going again. Luckily a very nice woman pulled over while we were stopped and told us to drive it into their resort a few miles down the road. We had it towed into Thunder Bay the next day and had the catalytic converter replaced. Ran like a champ after that.

If you can run a code check on it, make sure you are not getting any for the exhaust system. There are a number of things that can cause the symptoms you are describing, but the exhaust system is one that can be overlooked sometimes. Whatever it is I hope it is a simple (and inexpensive) fix.

Good luck.
