make sure you have power getting to your starter when you crank. check the small nut on the starter. should have 12 v or very close to it. this will tell you if your getting power to the starter or if somethign before the starter and something maybe with your anti theft system or not. its hard to say online cause of that anti theft. doest the light flash at all? the anti theft light?
if your getting power to the starter when you crank make sure your getting good power to the starter by turning on the head lights and see if they dim. a good starter will cause the headlites to dim when attempting to start. if nothing dims check connections. or assume bad starter motor. make sure your also getting power to the main starter stud as well.

The fuel pump is starting to go. The fuel pump sending unit which is part of the fuel pump is over heating in time and shutting down. This is causing the fuel pump to shut down.
I would replace the fuel pump and filter.
