Thanks for your help guys. I think I've got a pretty good direction to head in now. I want to order new plugs, wires, cap and rotor anyways just because I doubt any of it had been done recently. It will be a while for parts to come in, but I will be sure to update this once I get everything sorted.

I should have mentioned plugs, cap, and rotor as potential problems. However, the plugs, wires, cap, and rotor rarely will cause it to stall, just buck when you load the engine heavily. That's the kind of thing that the ignition module or failing fuel system would do. Still, it will certainly not hurt to replace them.

I do plan on replacing fuel lines, adding an inline filter and rebuilding the carb as well. It may not all need to be done, but it will give me piece of mind.
On the ignition side of things, I am going to do the fore mentioned as well as look into the ignition module, voltage regulator, and coil. I may just change it all for the hell of it to know that it's been done. Again maybe unnecessary, but I like knowing the state of components. Being a truck that's 8 years older than me, I have no idea what type of maintenance was done or when things were replaced.

The voltage regulator is part of the charging system and has nothing to do with the ignition.
This is just my opinion, but today's Chinese-made parts very often aren't worth crap (for very long) so, if you decide to replace parts *****-nilly, keep the old ones so you can put them back in the event some new part(s) doesn't/don't work (for real long).

The voltage regulator can easily cause weak spark if it isn't causing the alternator to keep the battery charged. A few years ago the regulator on the 82 failed and the ammeter didn't show a discharge. I was driving at night thinking the headlights were really poor when the engine started missing as I tried to accelerate. It would cruise just fine, but didn't want to accelerate. Turned the lights off and it ran great.

I fully agree that parts shouldn't be replaced "just because" since many parts we are getting of late aren't good. But don't overlook the charging system, as I said in my first post in this thread, since it can easily cause the ignition to throw a weak spark.

We still haven't heard from the OP if he has done any inspection of the fuel system or any testing at this point. If you throw too many parts at a problem you can make things worse, I agree.
