Ford F-150 2004 35,000 miles 5.4L: Going down the road I a small bump and the motor quits. Once I was going about 5 mph and went over a speed bump and it quit. I checked battery cables and starter wires and everything is tight. I checked all wires around the fuse panel and everything seems okay. Any other suggestions?

Shake it! That is, a wiggle test of the wiring with the engine running. There is a wiring or connector problem I would suspect that stops power from getting to where it has to go. Check pcm, bcm, fuelpump harnesses, grounds etc.
