Our 2009 Ford Edge shut off while driving. The engine will start and run for a bout 5 seconds and then shut off again. I can hear the fuel pump running so I don't think it's the pump. What could be the problem?

Well typically there are more fuel delivery related problems than ignition related problems - even though you are hearing the fuel pump it doesn’t necessarily mean there’s enough fuel getting to the engine.. Therefore it’s obvious *hands-on* testing is going to be required before the actual failure can be determined.. Too many possibilities for online guessing. Good luck!
