OK. I've been fighting with the car for a few weeks now. Every time it restarts, it loses one or more of several user settings. These include: display background and mode. Navigation preferences and breadcrumb features. Radio station. Preset tabs.
The battery has always been inadequate for the car. The heat has been brutal for the last few weeks which is also brutal on a battery. I spent time charging to see if it resolves. But I've even had the car lose the setting while driving and doing the power/>> system reset. So it doesn't seem to be a battery.
I considered heat or an aging, failing APIM. I tried to do a reinstall of Sync. It did not resolve the issue. In looking around, my version 22251 also has issues with other vehicles.

You'll find the same kinds of topics on Ranger, Explorer and other forums.
I ran the interrogator tool there as suggested and have the same issue.
It seems that eventually the Ford log files clog up the APIM storage. So yeah, getting a new module would fix this. Until it fills up again so that is more of a bandaid and involves giving your car to the stealership for a while. I ran a cleanup utility and got half the space back. It took about an hour of running in and out of the garage and doing Sync updates. That beat going to the dealer for help.
System appears to be functioning properly so far. Time will tell. If it does it again, I will just delete the directory again.
