2000 Dodge Grand Caravan will not start

My wife could not start our van this morning. Lights were on inside, starter clicked few times, but car did not start. I used the cable to jump start and she went away. It happened like this 2 month ago, same symptoms. I put new battery in and was OK. Now the problem is back?
I will appreciate any sugestions about this problem.

I would take it in and have the charging system checked. Also, if was starting to give some indications it was losing charge, such as turning over slow etc. Check it for a constant draw when shutdown. Make sure the insulation blanket originally on the battery, did not get discarded when you replaced the battery the first time. If it did, get another one, as heat under that hood will kill the battery without it.
