1991 F350 7.3 stalling

my truck keeps stalling out, it will idle fine and will stay running at a low speed, when I try to speed up it stalls and kills. I've changed the fuel filter and its still stalling.

Sounds like a fuel pump problem, probably need to check your injection pump.

Or your lift pump, check it and your lines for splits/breaks. Also check for volume to make sure the lift pump is even any good. Simple test to do.
