Every morning, I drive to work. I hit the highway and lock it into cruise control at 65mph. After 10-15 minutes, for a period of roughly 3-5 minutes, the revs will dip down suddenly, lurching my body forward, and then quickly recover. It's as if the car's computer decided to suddenly downshift from gear 7 to 5, then immediately changed its mind and went back to 7. It usually does this for 3-10 times or so, then drives normally for the rest of the day.

Any ideas?
