QuestionQUESTION: My 1999 Cadillac STS with Northstar engine will just die while I am driving. It is not in any pattern, and I never know when or where it will happen. It has stalled on the expressway while in cruise and when not, on city streets, and at any speed. I do not know why it happens. It has been doing this sporadically for about two years, and recently it has sporadically started just clicking when I try to start it. It will eventually start after anwhere from one to as many as 20 tries. Help!
