please help with 300..

Daughter has a 2007 Chrysler 300 with the 3.5. It died on her at a red light today. I tried and tried to get it started but it wont. It sputters a little every time I crank it over like its trying to run but just wont. Acted to me like its out of gas and getting a drop or 2 everytime I crank it the way it will sputter up and die. The fuel pump is indeed running every time I turn the key to run. I swore it was just out of gas but we put some in and still the same thing.. Any know things with these cars that acts like this? I have to help her some how..Im just not familiar with the new mopar stuff..
Thanks
how many miles on it?
