Drive to next exit just fine. Then got back on and punched it and it happened again. Restarted and drove fine. Problem recurred a couple of times. Drove to dealer today, they say it is the Vacuum Pump. I hope this is the last of it. SA said this is unusual. My car is '12 coupe 6MT with 15k miles on it (delivery date dec 2011) and is uber clean. I asked what it might cost if not under warrantee and the guy said $2500 to 3000 (Pump over $2k) In case this is wrong, he just guessed but that is a sobering amount of $$ for what may be an ancillary part. I will update when I get it back. BTW, other than oil changes and tires this is the only issue the car has ever had.

I had this happen after I changed the spark plugs...I did not get one of the connectors 100% "clicked" back on and it would fault under heavy acceleration (which made me think of your post). If whatever they do does not fix your issue, it might be worth keeping this in mind.
