Welcome Visitor! Please take a few seconds and 
I've got a '96 Ranger, 3.0, auto trans. The tach works when it wants to. I've pulled to instrument panel and cleaned the connections. I have looked over the wiring. There is no misfire when the tach cuts out. I was just wondering if anyone else has had this problem and what the solution was. I have also tried wiggling the harness, beating on the dash, steering wheel, all of the simple stuff that usually gives you a clue of where the problem is. As far as I can tell it is the tach itself. Any seconds?
