I had a very similar problem with our previous Focus in that when you cruised at a set speed for a while (minutes, hours), it would "hiccup" slightly. It wouldn't be enough to log a code or throw a CEL, but it happened once every few months.
I didn't keep the car long enough after the repair, but not too long prior to selling it we found out that a lot of minor driveability annoyances were related to the ignition coil. Once that was replaced, the car woke right up and drove well... until we sold it ;)
I'm not ruling out the transmission per se... try resetting the ECU entirely by leaving the negative cable off the negative battery terminal for 5-10 minutes. Then, reconnect it and drive the car as you normally would. Occasionally, take it for a quick jaunt to the upper rev ranges. See if it happens again.
When was the last time you replaced the fuel filter?
