Will crank no start

[Myhero85]

2005 explorer with 4.0, started then died, and will not start back. Left sitting about an hour will start and run for three seconds and die again. Changed fuel filter, fuel pump and crankshaft position sensor. No change in what its doing. Any one have any other ideas as to what's might be causing my problems?
