My girlfriend just had this same issue happen on her 2010 3.0xdrive and it turned out that the crankcase vent value was bad, but it is inside the whole crankcase cover so we had to get it fully replaced which was about $1200. The solenoids that help control the VVT were also going so we had to get those replaced which was about $400 but now it runs like new and have not had this problem since. Hope this helps.
