99 7.3 Powerstroke.
 

I just bought the truck and i think it has a injector problem. I plan to take it to BTS this week. But some reason driving down the road running about 2 grand it will stop taking fuel or something. You can just watch the rpms drop. then it takes forever to start. Anyone know what the problem could be??

Could be a fuel pump, could be the HPO pump... Hard to say without pulling some codes and data logging.

I ran my scanner on it and pulled 4 codes. 2 were ICP codes and one was the cam positioning senor and i dont remember the 4th of hand. But when i say it quit taking fuel i not real sure what it is doing but you can just watch them drop and it will die.
