Is the check engine light on when this is happening?
Ok, this issue is usually a problem with the mass air flow sensor. If you unplug it and start the truck and the idle is smoother it can be a good basic test. Usually though the best test is to have a scan tool that can see the live data from the maf sensor. This may also be a problem with your fuel pressure and fuel pump, but it's been my experience that it's typically a mass air flow issue. This can fail without setting the check engine light. All it has to do is read wrong and it will cause this type of problem.
