since it appears to happen at random, perhaps a little more info might help people key in on what may be causing it.
which engine?
cruise on or off when it happens?
one thing that comes to mind is a grounding issue that another memeber had..... his symptoms were different, but grounding can do some seriously wierd things. (BTW, i was the one that MISSED the nail in this thread
so take everything i say with a grain of salt

edit ...
something else just came to mind is that your mid 90's dodge products would do this when their Throttle Position Sensor (TPS) would go out. the TPS would go to Zero ohms, telling the computer that the engine is at full throttle causing the downshift..... not sure the new fords even have a TPS, being that the throttle is drive by wire ... but that's what came to mind
keep us posted
