Jess, I had a similar problem. Does it crank over and just not catch? That's what mine did. It starts after about 30 min of rest...really rough, with a little smoke too

. It did it during the winter, so I concluded it was bad gas or frozen gas. Dunno. I talked to the Ford place and they suggested a "hot start reprogram" or something like that. Can't hurt to ask about that. HTH, and good luck.
