ctsv ckp code at wot.. only in first

[rbsurfer]

Having a problem out of nowhere every time I floor it in first it sputters in and out but only in first. And if I do not let out quick the tach goes to 0 and throws a ckp code. If I turn the car off for 10 mins it is back to normal. By the way its a 2006 ls2 ctsv

Crank reluctor play, loose ckp sensor, loose battery or power cables.
It may also be a ground issue or bad wiring
