I have a 04 f150 with the 5.4 that just shut off like the key was turned off, the only thing that runs when the key is on is the fuel pump, i've checked the fuseable link & the hotwire on the starter & both are in good shape, I also have no power at the starter on the hot wire (crank signal)
any body have any ideas as to where i should be looking?

 

ended up being the fuel pump module shutting everything down, so if you have similar issues you know where to look
