I went to start my Dodge and realized that the interior light had been left on. When I started it the turnover was a little sluggish. It ran fine for the distance I needed to go. It sat for a day and the next day when I went to go somewhere it started fine but when it went to idle it died. I tried this several times and still it would die at idle. What could cause this problem?

Remove and fully charge the battery. Many auto parts stores will do this for free.
