1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic 135000 miles

I'm just giving this a shot but my 95 Chevy Blazer has been acting up for the past couple weeks now. It starts fine...I go to drive it and it doesn't seem to be getting the gas it needs...it dies on me sometimes as well. Starts right back off but then it repeats itself. Or some days..its fine.
I've replaced the alternator, battery, spark plugs/wires, starter/flywheel, and a fuel filter but it is still dying. Some people say fuel pump, fuel injectors..or possibly the ignition switch is bad which causes the car to shut off. It sometimes runs rough too. Not sure what direction to go..thanks.

Did you do any testing before you replaced anything?

Are there any codes? Some of the national brand autostores will check codes for free. My info shows you have that spider type fuel system and your obd11. There are bulletins on that fuel system, I can't tell if that's your problem or not. How's the fuel pressure?

The bulletin talks about the fuel poppets getting clogged or stuck.
