I picked up an 85 Cutlass a few weeks back and finally got around to tinkering with it. Well after it sitting for 5 plus years it started right up with a good battery. After it ran for 5 minutes or so it died. When it died the charge light flashed on, turned the key and had nothing then it just roared back to life. Ran a minute or so and died again, flashed the charge light and now nothing. I am just looking for advice where to start looking. Thanks
