2 new batt ,new fuel filters new oil filters checked and confirmed fuel at top engine mount checked ficm 48 volt ,had starter benched tested good and replaced altinator also checked all pulleys cranks really slughish and sound like something holding it from turning over

All other states "ready". I have performed 5 drive cycles as per recommended in the owners manual, another from the ford site, and another found on you tube as well as "just drive it some more" as the smog shop recommends. NO trouble codes have listed.
What's next?

I thought it was a fuel issue so I changed the fuel pump and filters but the same thing is happening and no check engine light is on

When I fill my truck up, the fuel gauge shows full until I get around 3/4 then it drops to empty. Sometimes (once or twice) when I turn off the ignition and back on it will show the correct level when it's below 3/4, until I turn the ignition off and on again.

It will always show full when topped off and then at around 3/4 full drop suddenly.

When it turns over will not even fire then when it does start runs normal with no power loss. Does not do this all the time

i change the altenator,power motor and battery,but still with the same problem.

I've had the truck in for service twice in the last 6 to 9 months to find the problem. Two different shops, the last a F250 diesel specialist shop. Both have told me it was the cam sensor. Today, 2 weeks after going to the specialty shop and having a new cam sensor installed, the truck shut down on me 4 times in a 10 drive. Engine was warm, driving at different speeds, both in town and highway. When it shuts down, as I'm driving, it comes back on without me prompting it or attempting to restart. You can tell it shut down two ways. Loss of power and the glow plug coil light illuminates on the dash. The specialty shop checked for loose wiring to no avail. The fuel is good. But right now I can't drive the truck too far from home.

But when I park down hill it starts right up
