I am having problems with my truck shutting off. It idles fine then will drive for a few minutes and die again. I have been having this problem for roughly a month. I figured it was a fuel filter problem, I replaced it and continues to do the same thing. I recently purchased an Air Dog 100 and filter delete. It started and idled fine but when I tried to drive it, it died again. I cracked the bleeder screw while the Air Dog was running and nothing happened. So, I then tried priming with the priming bulb, and the bulb was suctioned down and would not come up. I'm running out of ideas and need help. Thank you.
