You can watch the volt meter go down til the truck dies. Throws a crank & cam code. I have replaced the alt, crank, cam, & TPS. And it still doing it. Any idea what whats wrong? Can you test the ECM?

Check to see battery condition first, ifcharge then test, if lower than 12.4 volts replace battery check for charging as well if not charging check fusible link that connects to alternator if it's burn it won't charge. Then scan for codes and check fuel pressure.
