HELP! car dies when hot.

Hi Guys, I have been working on this problem for months now and getting frustrated. 1951 Packard 200 Deluxe Ultramatic. Car behaves perfectly until it gets completely warmed up. If I take it downtown, chances are I will be limping the car home or towed (once).
Fuel tank is clean, fuel line is good, rubber fuel line is new, fuel pump rebuilt from Kanter and carb rebuilt. In the shop the glass filter bowl stays full until the car warms up and then the fuel level drops. The fuel will spurt into the bowl for a few seconds and then stop completely, then spurt again. Sometimes it runs out of fuel completely. Gas cap on or off makes no difference. I ran the fuel line into a plastic jug and got around 2/3 cup just cranking the starter for 30 seconds. Is this enough?
Any help will be greatly appreciated I am completely at a loss. Dan
