Why would your RPM gauge stop working then cause the car to cut off all of a sudden in a 1989 Mercury Cougar Xr7?
Your RPM gague (Tachometer) is a "dummy" system, and has no feedback to the engine itself. This means that your gague is a symptom, not the cause. I would advise you get the electrical system checked out. Another possibility is a bad computer. I saw this on a Chrysler car of the same age, and it caused all sorts of havoc, including a zero reading on the tach.
