Sounds like you need this part
ebay item 170761661156 (im not the seller for this part)
i had the same problem my car would start and stall at red lights.
I finally got to a point were I had to hold the key in place.
I checked at my local auto parts store and was looking a a $100+ part. They wanted to sell the unit when all I needed was the wiring.
