I'm Having Problems With My Truck It Runs Fairly Well Unless You Push It A Little And When It Hits Second Gear It Just Flattens Out And Tries To Die, I'm Getting A Trouble Code That Says It's Running In Femca Mode Or Something Like That I Was Wandering If Anybody Else Had This Problem.

I'm not up on all these fancy engine codes etc., but from what you say your problem is I would be checking out the fuel pressure to the injectors, you might have low fuel pump pressure if it dogs out on you.
