I had the same problem with my motorhome. I don't know about your F250 but it sounds like when you are in start mode the fuel pump is on, when you are in run mode it shuts off.
On mine there are several switches it has to go through to keep the fuel pump on in run mode. Mine has 2 vacuum switches, an oil pressure switch and a rollover switch...And of course the ignition switch
In my case a connector for one of the vacuum switches melted on the manifold and shorted out.
Maybe someone with attachment posting privileges has a schematic they can post.
