Don’t know how old this post is, but it sounded like something similar to what I had. Although maybe not. I have a 2001 Town & Country and I came out to start the engine to leave for work and it ran for about 15-20 seconds and then died. I tried it a couple more times and it did the same thing. I honestly couldn’t figure out even where to start diagnosing it. But then I tried starting it and then when I step on the gas, it dies.
I then turned off the engine and just turned the key on and could hear some kind of electrical almost a static-like sound coming from somewhere very near the alternator. So that makes me believe that it’s an electrical issue now and could be the alternator.
Any thoughts?
