Automatic Transmission Control Module problems of the 1999 Cadillac Catera

I contacted the bbb auto line and someone from gm(ms cass brass) call me offered me an extended warranty> then ask me if I was taking that as a settlement advise her no. I want my car repaired r replaced. She advise me 2 drive d car 2 c if happen again. I explain 2 her I'm really scared 2 drive my car . I'm scared that it may stop on me and someone hit me & I cause a accident> I explain the same thing 2 d dealer when I took it each time it cut off. On my 1st notes I explain that my car just cut off while driving it on 5-20-00 I was driving 50 mph when my dashboard lit up and it just cut off it did it 3 times within a 30 minute period. The 1st time it cut off was 3-7-00 5896 miles on car, next time 4-28-00 , then 3 times on 5-20-00 the dealer sd they replace pcm/vmc also said pcm reprogrammed, myt car drove fine until 12-20-00 when it cut off again while driving then on 12-30-00 it stall got real sluggish like it was going 2 stop but didn't.
