Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

If the tach and speedometer act erratically and the engine dies then I would rirst suspect that the engine controller is going down, whether it's due to ain internal failure or a loss of power or ground to it.

The first step in diagnosing the problem is to use a scan tool or code reader to see if any fault codes have set. Have you checked for codes?
