Fuel Problem, Took Duster for a Shake-down Cruise

Well I got the Duster out and decided to take it for a shake down.. I wound up pushing it home the last 100 yards.. Boy was I PO'd.. Here's what happened.. Ran great, got up to temp no stutter, hesitation, everything was good. Cruised around for about 4 miles (in town). On my way home I sorta punched it and it almost stalled, then it picked up and I got up to speed quick. (good thing cause thats what got me within 100 yds of my house, coasting) Then it just died... So while coasting I put it neutral and started it, started right up.. then stuttered, fluttered, and died again. The sound of the starter reminded me of the sound my Dad's old "C" bodies he had would make when they vapor locked..
Got it in the garage and yanked the breather off, looked down the carb pushed the linkage and no gas.. Took a fan and put it on the engine bay and waited about 30 min, came back and it fired -up for about 15 seconds then died again. So I looked down the carb pushed the linkage and no gas.. The engine is brand new rebuilt warmed up 318 (323 technically), the carb is a new Holley 600, just for information sake.
Now I ran the car out of gas (by accident, gas guage doesn't work) while tinkering with it after the engine was rebuilt. It has a new steel fuel filter, not plastic see thru, I'm wondering if it could be plugged because of my little incident of running it completely empty, or if the tank is just nasty and it's filling the filter. It is the original tank, I was going to hold off and replace next year with a new one, or the brand new fuel pump just ain't suck'in right, or maybe it is vapor locked, or just maybe all 4, in which case that would really suck...no pun intended.
The fuel line from the filter is a rubber line that runs up through the alt bracket and lays against the water pump/timing chain housing into the carb, the fuel filter is actually below the alt pointing straight up on a piece of steel line bent like a "J" so it's atraight shot. And I forgot to mention the fuel line coming from the tank is like 1-1/2" from my passenger side header, stock position.. So I guess my question is, Ya think it might be a combo of everything? I'm gonna change the filter see if that makes any difference, I was always taught start with the simple and obvious first before R/R'ng everything and not troubleshoot it..
I'm open to any suggestions and experiences.. I don't feel like pushing this car anymore..(I hope! LOL!!!)
