I'm with dan I didn't hear the bottom end falling out... If it were it wouldn't start like that !!

I'm thinking Vacuum Leak...

When it runs can you keep it going with the go peddle ??

Your truck doesn't have a MAF. Since it'* a stock TBI, it has a MAP sensor.

If you want to eliminate the EGR has the problem, try unhooking it at the throttle body and plug that port on the throttle body. If it still doing the same, then it'* not the EGR.

I'm thinking the MAP sensor could be the problem. Try unplugging the 3 wire plug at the MAP sensor and then try running the truck. If it solves your problem, then it'* either the MAP sensor or one of the 3 wires going from the MAP sensor to the computer is bad. I've seen one of the wire going to the MAP sensor go bad before, one on a 95 Silverado and my 92 Caddy. Both vehicles ran so rich, it would kill the motor.

That'* my 2 cents.

Here'* a little test you can do. have someone start it, then use starter fluid and spray a little in the intake. Just enough to keep it running. If it keeps going with the starter fluid, then it'* fuel. Slap on a fuel pressure tester and see what you got. From the sounds of the video it seems like it'* getting pressure at KOEO and as soon as it starts the pressure drops off. I'm thinking bad fuel pump.
