2003 F150 stalls when started

My '03 F-150 will stall at random when started. I took it back to the dealership and they did not have a clue what was wrong. The truck is all factory parts. After it stalls 3-4 times it will start and run fine. Has anyone else had this similar problem?

Well on the powerstroke diesels, this would happen with the crank position sensor goes bad. I call it intermediate CPS failure. Try changing that and go from there.
