ok, when i drive to work its about 30 miles and when i get to work and park and shut off car and wait about 5 minuts then try to start it it dies

 

i had similar issue, defective battery cells, warranty replaced the battery for me, for a while i was driving with an electric jumper in my trunk

 

Does it eventually start if so I dont think it would be the battery if it turning over fairly quickly when it wont start.If your boosting it to start it then yes the battery it is.
If not then,
Try turning the key on but dont start itfor aabout 15 sec and let the fuel pressure come up before trying to start it.
Could be your fuel draining back or the pumps going.

A quick check for the battery is with a meter to see if you have 12v on the dc or straight line setting on the meter.If you only get ten then you have a dead cell and the car would need a boost to get it started.
