2006 F250 stalled and quit

[PJM]

These motors seem to very reliable and was out fishing on and backing up and the motor sputtered and quit running. Motor turns over and you can here like the fuel pump start up when you turn the key on. The motor has a water separating fuel filter and the fuel filter on the motor seemed fine on the motor and did not see any water. The motor will not fire at all and all the fuses look fine and the safety lanyard is on , any ideas.

Check spark with spark tester and check fuel pressures to see if they are in spec
