    05 F350, bottom line, the engine cuts-out for about a half second, completely randomly. So when at RPMs it's just a stutter, at idle it's a stall. After the cut-out, the injectors rattle, like a fresh start. Which component is the one that actually rattles the injectors?

    Replaced the ICP sensor (it tested bad) ICP is good, replaced the cam position sensor. A bunch of other stuff is fresh, less than 10000 miles on HPOP, IPR, injectors. FICM voltages are good 13ish in 46.5 to 48 out. Fuel pressure 60lbs.

    Any ideas?

    With the injector buzz again, the FICM or PCM is loosing power momentarily. When it gets power again, it runs the inductive heating sequence. It thinks the key has been turned off and back on.
