now i know the both my modules tested fine but someone also said there modules tested fine also but they turned out to be bad.
guys im so confussed,lost,upset,pissed off
im a pretty mellow guy but when things like this happen (unknown engine problem) it is so damn hard to keep my cool.

If your ignition module goes bad it won't fire at all. You could be driving down the road running just fine and it would just die and never start again.
Did you try grounding the dizzy like I suggested before?
Get some wire and run it directly from the hot cable on your battery to the hot wire connection on your dizzy. See if this makes any difference.
If you have another coil try sticking it in and see what happens. Why did you replace your coil 2 months ago?
You said you replaced the pickup coil inside your dizzy. Is it adjustable? If it is you may need to close the gap a little.
You said you set the timing for 4 degrees before tdc. Did you do this with the vacum advance disconnected and capped off and the engine idling around 800rpm? If not, fix this first and go ahead and set it for 8 degrees.
You need to check everywhere for a serious vacum leak. Vacum lines, brake booster, carb gasket (make sure carb bolts are tight) intake manifold gaskets (make sure all intake bolts are tight) spray starting fluid along the edges of the intake manifold where it meets the head with the engine running and see if your rpms jump way up.

Your vacum advance won't cause this. If it quits working you will just lose some power and mileage but the engine will run fine.

Not unless it's grounding out. You can disconnect the alternator completely and start the truck to see if it makes any difference. The truck will run fine off the battery for a while. In fact, check all your hot wires including the battery cable and see if they are grounding or melted onto anything metal.

Yes it can.
What's the chances of you being able to take a bunch of pics of your engine bay, carb, inside the dizzy/cap, etc?
