The fuel pressure regulator seemed to be fine. It was tested and was sitting right around 28 pounds of pressure at idle. and up to 40 pounds when it was revved up and held at 3,000 rpm. When it was shut off it held the idle pressure for 15 mins afterwards.
The fuel filter was taken off and replaced because there was actually a lot of resistance when trying to blow through it. But even then, it only increased it 1 pound.

I did not get around to checking the spark after it shuts off chevyh8ter.
Turns out what fixed it was putting in a new drivers side oxygen sensor. I guess it went bad at some point all of the sudden. (id expect to notice signs of it going bad instead of it just completely giving up all of the sudden like it did.) I think that because the o2 sensor degraded and could no longer operate within the temperature threshold, once it got too hot it started sending (or not sending at all) the correct information the computer needed. So the computer would be panicking to solve the issue; i.e. - holding back on how much gas was injected into the cylinders which the engine needs to run. And little by little the engine would get less and less gas and would end up "acting" like it ran out of gas and just quit.
That's just my thought.
Its now driving like itself again with no problem at all. I actually think it drives a little quieter down the road now too. Even for the catalytic converters being busted out of it.
And hopefully it gets better gas mileage than it was before after having cleaned that MAF sensor. (which I'm guessing brought that o2 sensor's demise.)
Normally its rated for around 18 miles per gallon when driving in the city. But mine hardly ever got any better than 10 just driving it around town.
I thank and appreciate both of you guys for your help!
One more thing Rick. I think I've located where my engine is leaking coolant. I believe its from the freeze plugs. Should I go ahead and make a new thread talking about all of that? Like whichever ones I should use to replace them with; i.e. (rubber or regular metal plugs) and whether or not I should replace them all at once. Under the thought if one is bad then the others are on the way? (right thinking?) And if I should replace them all then I think i should pull the engine out. And then ask where I could find detailed instructions on how to do that. (if it's needed) And while I have the engine out if there are things I should go ahead and look at and replace while It's easily accessible.
I'm asking because I feel it'd be a little irrelevant to this thread title. ( and honestly after writing all of this I'm thinking more and more that I should just go ahead and make a new thread about this. But because I've already got all of this written, ill just leave it out of curiosity of whether or not you'd be able to answer all of those questions. (if its not too much of a pain.
))
