1995 1500 5.7 Will stumble at idle, stall, and not restart
I'm at a loss for this darn thing, so here goes. I've got a 96 half ton with the Vortec 350 and 4L60E. Recently pulled it out of my backyard after sitting for a bit because it's my only vehicle with a/c and I live in Texas. I have replaced the fuel pump because it was bad and the other following bits because I read they can cause problems or because they set codes
Crank sensor
Cam sensor
Coil
ICM
Cap, rotor & plugs
EGR valve
Fuel filter
And still my problems persist. Last week it was running fine. Then at the last stoplight on my way home, it started to idle rough. When I let off the brake and hit the gas to get moving, it sputtered and died. I was able to restart it after a few tries and get it back home. Today I finished installing those parts I listed, along with verifying my timing is correct. I went to take the truck on a test drive, and it was idling okay until it stumbled twice and stalled on its own. Now it won't restart.
I'm at a genuine loss. Somebody help me please figure this hunk of shit out. Photo for attention, I guess.
