I know you ruled out fuel but two other places notorious for intermittents is the flex hose between the pump and the fuel line hard connection below the radiator and the fuel pump. The inner lining in the hose can crack and pump suction causes a section to pull away and act like a flapper valve stopping flow. There is also a screen in the bottom of the fuel pump. If the gas tank is or was rusty, the bowls are known to catch a lot of rust and suction pulls enough up to clog the screen. When engine dies the suction stops so rust settles down after a few minutes or the flap in the lining relaxes and all works until the cycle repeats.
