1964 b-67 non turbo. truck will run awesome and drive great for about 1/2 hour. Then it will start to sputter like its running out of fuel, then eventually die, we have to wait about 20 mins, then bleed air out of the injection lines (sometime it will just fire right up without bleeding), then she fires up and runs pissa for another 30mins. I figure its sucking air but all the lines seem fine and if it were sucking air I figure it would only run for a min or 2. What else could it be? Truck has only 155k on it and its a very clean motor, pump was never turned up or fooled with. Thanks for any ideas in advance! -Pete
