I have a 2007 328xi... I purchased it off a lease at roughly 54k miles. One day shortly after taking ownership, I was cruising down the highway at roughly 70mph and everything glitched like you just said. Scared the bejesus out of me. It turned out to be a Vanos problem. There's actually a SIB out for "dirty vanos" issues where they sometimes "stick". I have no idea what the vanos does or how it works... All I know is they cleaned it out, and it hasn't happened in 56k additional miles... (they didn't replace it, they simply cleaned it).
It threw a code so the dealer quickly knew what was wrong.
