Have you determined it is positively fuel related? I haven't heard of the hose being a cause of vapor lock but have had experience with old hose that dried and the interior lining was brittle & cracked. Suction from pump pulled a piece of cracked lining loose enough so it acted like a valve stopping flow. Engine quit, suction relieved, lining went back into place all well until it happened again. If still original hose, would suggest replacing it whether cause of this issue or not.
