Stumped by intermittent problem
For the last four months my 04 F350 has been having the same problem every now and then. Cruising down the highway at a decent speed and the fuel pedal/fuel shuts off. Only lasts seconds then re-engages. Two lights come on. Low fuel and water in fuel. I changed the internal fuel pump last week and it did it again tonight. The truck runs great otherwise except for an occasional death shake while stopped at a light. No codes came up and FICM is at 54. Any help would be appreciated. Exhausted by my brothers wait till it breaks completely attitude.

Have you considered fuel pressure? Maybe a quick blue spring kit will revive the fuel delivery since you have done the pump. The new fuel pump could be resurcularing the fuel to the top of the motor and right back into the tank if the spring is shot.

Additionally, are you certain that you have Motorcraft fuel filters upper and lower, as well as a Motorcraft fuel cap covering the upper filter?

What would the glow plug light indicate?
Just curious.

Help me understand, sudden power loss leading to PCM reset would drop fuel management and air management immediately, resulting in visual of the glow plug indicator as the PCM resets, then the motor is ready to go again.
Would the glow plug indicator come on for sub-second of time or more of a normal heating cycle?

It's like turning the key off and back on. Every time the glow plug light will come on but does not necessarily mean they'll cycle at all. The light really has no indication of cycling.
All beside the point if the OP isn't seeing it.

Only Ford Fuel filters, cap is correct. I have had this truck for 12 long years. This isn't a normal issue.

Put 4000 miles on the truck since this first started in August. Lots of different fuel from different states with additives on top of that. It does seem like a sudden power loss. It only lasts seconds. My brother has a new rule. It is called, "Don't shout it out!" That means don't wake him while we are driving unless the truck is dead on the side of the road.

I would try this, it certainly smoothed out my 2004 motor with 200k miles on it.
