Issue with a 2007 Dodge Grand Caravan
 

I have a 2007 Dodge Grand Caravan. This past Saturday morning, it was working just fine but later in the day, I tried to start it, nothing happened, no sound of the starter. I thought perhaps the issue was with the battery. I went out and purchased a new battery. After replacing it, I tried starting the car again, nothing happened. I thought at that point that it might be the starter. Later in the day my son tried it again, it came on but it won't stay on. I tried it several times, comes on for less than 2 seconds then it shuts down. Could you please help me understand this issue before I take it to shop... Thank you!!!
