1ftpx14v17fa93060 (2007 FORD - TRUCK)
2007 Ford F150 1/2 ton P/U 4WD
8 Cylinders V 5.4L MFI FFV SOHC 330 CID
Engine stops dead. Doesn't chug or hesitate. There is no common precursor to it. It just dies.
No engine light. It will start right up afterwards.
While driving on the highway, it never dies.
(Has new fuel filter and pump ... new parts installed by dealer in his attempt to fix this)
Otherwise, the truck runs fine with the standard Ford Triton clack.
Any ideas?

It has to be tested DURING THE FAILURE to accurately diagnose anything so any advice here is nothing but a wild guess but the symptoms tend to point to a Crank position sensor or it's related wiring.
