thanks... your dead on! it finally threw a code. actually two codes for the throttle control module. i was thinking this am that perhaps the speed sensor is defective causing my hessitation and trans to shift early but then while on the x-way at 65 mph the car just shut off like the key was turned off. fortuneatly i was near a rest area and rolled in. when at the rest area the gas pedal didn't work. i would press it and it was as discribed before, nothing. as if the car wern't running. that's when it threw a code. i have all data at my shop and found that there is a service bulliten also. thank you for taking the time out to answer the post. much appreceated.
