This is a wild longshot, but have the rubber fuel lines been replaced? Old lines rot from the inside out, and the inner part of the line can suck closed under prolonged suction, causing a stumble or stall on acceleration. Shutting off the engine and ceasing suction allows fuel to flow again, but is repeatable. I've had this happen on several of my '60's Fords and my '37 115c. Lines looked fine on the outside, but were soft inside and had separated from the nylon cord centered in the cross section of the line.
