The same thing happened to me in my 2003 boxster in a tight left hand corner on two different tracks. It would let out a puff of smoke after the corner and then flash the engine light. First time I replaced the AOS but no luck.
The next track day it did it on a tight left corner twice. I started taking that corner a little easier with no problem. A little later on I went through a little quicker and big smoke, very little power and the engine light flashing.
I limped it back to the pits put it on the computer and things were not looking good. I had it towed back to the shop and torn down and it was catastrophic failure in the heads.
One way to check if its the AOS is pull the MAF its super easy and if its oily most likely its the AOS if not its internal.
