Question Won't stay primed

I have a F-350 4x4 with 65,450 miles on... New latest problem is that I replaced the FICM and the fuel pump and now I can't keep it primed. The top fuel filter will fill then the truck will run for 2-3 mins and die... I take the filter cap off nothing in it. Turn the key back on fill the filter up put the cap back on... fires up again. Just won't stay running. Any idea's?

sounds like air in the system/vapor lock.

So any idea on how to fix that?? My brain hurts from this truck... It is my husbands truck and he has been out of town for 4 weeks and his cousin and my son have been working on it.

im not an expert on here but i belive there is certain start up procedures for when you change one or both the items you mentioned. I would search the tech folders on here 1st. and i know bismic would know more than me on this. it would be also good to know the fuel press prior to the repairs and now to see if there was a fuel press problem and if so was it fixed by these repairs??/
