my 6.0 powerstroke lacks power and in the mornings when I get on the entrance ramp and floor it, there is no power right away and when it does kick in the engine bucks and jerks. after about 5-10 miles or when the engine warms up, it runs fine. after I shut the engine off for about 30-45 minutes and go to start it, the engine starts and idles real low, likes it's starving for fuel then dies.

well i would hope you would not start it and take off and floor it withOUT letting it warm up... if so then that is your problem   if you do let it warm up completly before flooring it and it still does that im not sure what the problem is.   i no my moms 6.0L can barely move when she starts it and goes without letting it warm up... been when its warm hang on!!!  haha anyway    if you do take off with out letting it warm up that is your problem.  

my 06 is a dog unless it warms up. almost to operating temp. then she runs good  

you gotta let it warm up before driving it. it aint a gasser where you can start it up and go.
