My .02 is pointing towards the torque converter or a sensor.

 

Son, you need to have a talk with the Renix Gods... Hunt down BlueXJ for this one

 

Talk with BlueXJ,

but I'd also say look at the driver side motor mount, not sure how that would have anything to do with the cutting out but does cause shacking..

 

some fuel problem or u have a fed tranny but none of my renixs done this

 

After turning it off for a few mins does it work again?

Its not a fuel problem ive ever heard of... shaking is something more serious i had a 98 malibu that did this, after it warmed up for a while it was fine until i slowed down turned out the torque converter was bad..

any other times this happens?

 

it does it everytime i go over 45. it almost sounds like the motor is running different thats why i thought fuel problem of some sort. it also takes 8 or nine turn overs befor it starts not sure if thats related or not.
