Try cleaning your Throttle Body. See if it is carboned up, that will cause your truck to die when being put in gear. If that is clean then you need to pull the codes and see how the Computer System is doing., like are there any EGR codes, or tach signal codes etc.

Depending on engine, most fords have Idle Air Controle valves. They go bad all the time. Take something and tap on it while the truck is at idle, then try to put it into gear. You can also pull it off and clean it out with carb. cleaner but that is not a final fix.
