This could also be caused by a fuel tank full of rusty crud, the pick-up
tube could be clogging up and cutting off your fuel supply and after a few
minutes of no pump pressure the crud will fall away form the tube and your
car will start again. I had this happen to me on my 73 B when I got it. I
cured mine with a new fuel tank but I have also fixed my 74 B with POR 15
gas tank sealer which IMHO works very well. Good luck...Don Walton
