Won't Start! Emergency!

Yesterday morning on the way to work I turned off the car in a buddy's driveway to wait for him to come out and when i went to start her up it would crank but no start at all. Just crank crank crank. I took out key then watied about 2 minutes then it started up fine.
Now this eve when i got home I turned her off then about 20 minutes later I tried to go out and same thing again except this time she's a no go at all. Just turning over and over but won't start!
I know this is a warranty issue but of course the dealership is an hour away and closed. Problem is that I have a child here with very high fever and am waiting for my second car to get home to take her to the hospital. That won't be for an hour or so.
if anyone has had this issue and found out what it was and if it's a quickk fix please let me know cause it might be quicker.
Could it be the immobilizer? Where is that antennae? Is there a wiring harness near the fuel rail that could have not been clipped and shook loose?
The fuel pump does activate when the key is turned. Everything seems to check out but just won't start this time.
thanks all with any input!!

Cheers.
Shan.
