I just got this 95 gt convertible. when driving down the road it just dies as if you shut the key off. i replaced the fuel pump, tfi ,distib, ignition, car still shuts off sometimes takes it a few to re-start some times it just starts right back up. any suggestions? no mods that im aware of. it is a automatic . I also replaced the o2 sensor before the cat which is the number 3.
