I ended up taking my S-10 Blazer into a shop and have them fix it.

They found out that when the engine started to bog down that loud noises were coming from inside the fuel tank. They pulled the tank and along with a faulty fuel pump the inside of the tank was loaded with crap. All this combined to make my fuel pressure gauge needle flutter like wild. They told me when they had it hooked up to their machine that when they sprayed carb cleaner through the intake that the engine rpms increased and thats what led them to the gas tank and ultimately the fuel pump.
The pump was under warranty but I guess when the parts store asked about tank contamination the warranty went out the window. After a thorough tank cleaning and installation of a new pump and fuel filter its running like new.
I cleaned out the tank as best I could when I put the old (new) fuel pump in it but evidently I didn't do that good of a job. Only lasted a few months before the crap in there took out the pump.
Thought I would pass along what transpired to all of you. Thank you once again for all your advice.
