11 years and 121,000 miles, she is no spring chicken. But here is my issue or should I say issues.

When I start the car, I get a delay. I have the key all the way forward and I get nothing. Then (only occasionally), it starts, shuts offs, starts back up. All the lights on the dash stay on but the car runs as normal. I shut the car off, wait a minute, starts right back up. After driving for a short period (couple miles) and park, when I leave I get the classic dead battery when I turn the car over.

What could be the issue? Need a new battery, alternator or starter?

As a side note, three years ago, this car was a daily driver. I would drive this car over 200 miles a week for work. Since then, I have put a total of 3700 miles on the car in the last 20 months.
