I am having the identical problem with my 95 Buick Park Avenue and I could have written your e-mail with the exception that my car has to be in park to restart it. It's like someone pulls the plug. The electrical system shuts down so I have no warning lights, turns signals, etc. Lately I have noticed that it takes about two times to start it when it hasn't been running whereas before it always started on the first try. It always starts back up after dieing and dies once or twice a day at this point.. except when I take it to the shop and then it doesn't act up! Can anyone help us?
I have a 97 Buick Park Ave and I have exactly the same problem. I'll die sometime when costing down
