OK well here's the deal we got the truck for free so we turned it into a mud truck :)

Now About the problem, most of the time the truck runs great but usually after a few hours if starts to flood it self out. It the only way to get it to run is just run it wide open. When I pulled the intake you can see the injectors are dumping fuel. After it sits for awhile like an hour or sometimes a few minutes it starts to run perfect again.

I can't figure out what makes it randomly start pouring fuel in.

Any ideas?

Fuel pressures often "Spike" on those vehicles. Get a fuel pressure gauge set up that lets you monitor while driving. Generally a faulty regulator, but the regulator is inside the throttle body itself.
