Been down that road several times with trucks, not Ford, but doesn't make a difference. I also work daily with electronics that depend on steady relaible power to function correctly that also can throw codes, etc. Can't tell you specifically with your truck, but I can tell you the first thing I do when I get to a job with an electronics issue is hook to the power source I carry with me in my truck so I know I have good power.

My two cents worth,

Loose connections are very bad, low power for ficm is a killer and expensive. I would make sure cables are tight and drive it.

First time I had a truck flat bedded in years ago, nothing except loose terminal. There are, of course other things that can make a truck act goofy, but intermittent power certainly could be one of em.

In terms of troubleshooting, problems that are not constant are absolute Hell to find. Somedays I work my butt off and find nothig. Two weeks later customer is complaining because I didn't fix it. It's just hard to know for sure what was going on, but one thing for sure. No tech can fix a problem that is gone when they work on the truck. The problem with codes is they are not always correct any more than the computer in you den is always on top of its game. They are just machines and they don't always work the way they should.
