Have trouble turning it on then when I do I drive it for like 10-20mts

My ford 1987 f-250 4x4 6.9, then it turns off wat could be the problem?

i replaced new diesel filter, new batteries, replaced old diesel from tank an put new diesel in it, new starter, my injectors were leaking from the hoses up top and the rings I replaced and put new. Every time it turns off on me I have even more trouble turning it on the nex time until it dont start anymore and I have to use starting fluid about every time to start it too. When I put it on 4x4 it makes this like crank noise like its look or something and it wount move even thow I press on the gas?
