1998 Ford Contour car dies while turning, or just won't sta

While driving my car, and I'm making a sharp turn, my car will just die. Sometimes it will start right up. Sometimes it will not start. Also, there are times when the car won't start. I replaced by battery, I have replaced the spark plugs, fuel pump, altenator, put in clean fuel filter, have replaced the clutch slave. Other than this "starting" problem the car now works and sounds great. Could this problem be electrical or a bad sensor?
