This is a 6.9 diesel, its starts right away, then after a few moments it struggles and usually quits (sometimes it will stay running) and after lots of cranking it'll start again

Once it gets running, how does it act?

Sounds like the injector pump. There is a check valve where the return line comes out that gets clogged with debris and will cause this issue. If it is, then the pump will have to be replaced.
