My wife has a 2008 Magnum sxt 3.5 last night she came out of the store and it turned over once and stopped.Tried jumping it with a small car and it would only do the same.I bought a new battery and installed it,it was fully charged,it turned over exactly the same way as the old battery.I hooked the old one back up and then had my son come by and we jumped it with his full size truck and it started right up.Drove it home and it started fine and drove it in this morning to work and it started fine.I am getting the battery tested later today any thoughts on anything else it might be?

 

Get the battery tested and report back.

 

Battery is good,in fact both batteries were full charge,the guy there was telling me he had heard of spark plugs causing a similar issue.I found one post on here and it describes what was happeneing almost to a tee,,
