I have a 2014 F150 XLT 5.0, on two occasions it would crank very strong but wouldn't turn over, but after about 10 or 20 minutes it would start, this is in about a 2 week period, is this a fuel pump problem or relay or what?

Sounds like fuse 27 issue. See if it's melted or showing signs of getting hot. More info.... https://drive.google.com/open?id=0B6...nhOT0czZlF5M1k

Yep! Check the fuse like stated... especially before looking at more expensive options. Same thing happened to me before, and just had to replace the fuse.

Now i I just carry around a set of different sized fuses just in case.

And, get a $20 fuse relocation kit from E-Bay or local dealer. Fix it yourself or pay a mechanic to do it for about $125 and problem solved. This is TSB 15-0137, fuse 27 relocation kit and it has been out there for a while. Would not take it to a Ford dealer. They will charge about $150 to diagnose and maybe not diagnose right, replace wrong parts. Most report $400 or more taking it to a dealer. Good luck. This is where we are with Ford dealer service now.

Thanks for the help that's exactly what is was, but why do some guys suggest a fuse relocation kit, is there a problem with the fuse box?

The fuse box is melting right along with the fuse, that is why Ford came out with the relocation kit to put it in #70 instead of #27.

Some guys are just spreading the word that Ford set forth, The issue is they screwed up to begin with using too small of a contact area to supply the needed current, thus the relocation to a larger contact and larger fuse. The current flow is the same.
