daily driver in peril

Well fellas the 85 s-10 is acting up on me and I need some advice on the culprit. Recently while riding down the interstate the truck acted like it was trying to cut out. It started jerking real bad almost like the fuel was cutting in and out. It did this for maybe 10 seconds and then quit. It did the samet thing on the way back. This little burst happened twice on long drives but up until today that was it. On my way to school this morning the same thing happened but it didn't quit. The truck jerked and sputtered for about 20 miles or so. The best way to describe it is that it feels like the gas and brake are being pushed back and forth rapidly. I don't know if it's fuel related, transmission or what. Thanks for any help.

not sure if this is related, but I had the same symptoms in my winter beater - a '91 Buick Park Avenue. I would lose power, then it would come back. It would sputter, stall out, etc. After scratching my head a few times - it turned out to be the computer acting up.

Once I replaced the computer - it runs fine.

I'd start simple by checking the plugs and wires. See if you have a wet or excessively black plug, might be fouling out due to spark problems. Check cap and rotor too, could be going south. After that I would check fuel pressure. See if you can get a fuel pressure gauge tapped into the fuel system somewhere, SAFELY mind you. Route it away from any heat sources and the throttle linkage, and tape it down to the windshield so you can see it while going down the road. See if it drops when the truck starts bucking, might be your problem. That's a good starting point for ya.

Check the slip on conectors on the top of the coil. Mine on my 83 came loose and it acted like that. Bad conection that was touching at times and not at other times.

UPDATE:

alright after reading the suggestions and talking to a mechanic I worked with I started checking all the ignition parts. First I replaced the plugs and wires (needed it anyway) and the next step is to check the parts on the distributor. The news is that this morning when I cranked the beast up, it run real rough for a minute then cut off. All attempts to crank thereafter were in vain. It turns over fine but theres no fire. I can hit the throttle linkage on the carb and here the gas in the jet. As for a computer of such kind, there isnt one. They didnt start putting those on the s-10 family until they used fuel injection.

If anybody's got a good bike I'll run this POS off in the pond and pedal to school.

cap and rotor should be done next. I have fixed a similar souding problem on a 4.3 liter chevy by replacing the cap. One of the electrodes were corroded really bad. However, it would start up just fine. You are getting more serious problems now. Could also be a bad coil.

Check your coil. I had a 85 that would act similar. turned out the coil would get dirty between to wire connections and short out. I solved the problem by taking out the coil washing it with soap and water rinse and dry thoroughly than coat it with polyurethane.
This would last about a year before I had to do it again. Moister also made it worse thats why I would coat it to seal it.

Since it left me stranded yesterday I tore it down a bit and found that the plunger on the EGR valve is stuck and will not work. I also found some vacuum leaks that I missed the last time I went to fix them. I finally got it to crank up last night but it seems to flood and the pedal has to stay depressed or it shuts off. When I fix all of this, Im gonna check the coil before I put it back together. Don't know what else to do.
