1993 chevy silverado problems
I have a 1993 chevy silverado 4.3l V6!
It will crank when it has been sitting an the engine is cold, but once it warms up it Boggs down and shuts off, unless I keep my foot on the accelerator them it stays running until I let off and it idles down! I have replace the fuel pump, fuel filter, throttle positioning sensor, EGR valve, PCV valve an the idle air control so I'm at a loss right now... Anyone know anything that can help?

Welcome to the forums.
In all the items you replaced..... you didn't mention if you checked the fuel pressure. High fuel pressure can cause that problem.
