P0068 MAP/MAF - Throttle Position Correlation

We went to a track day yesterday at CMP and it did great on my first shake down run but the next run, I pushed it a bit more. Doing so would pop this code and the car would not accelerate, slow down and die. I could turn the car off then start it up and go but then it would do it again in half a lap. It is perfectly fine with normal driving.

any pointers in the right direction would be great, I looked for a vac leak but didn’t notice anything. My thought is the throttle body maybe
