Help Please, Truck acting wierd loss of power

I have a 2001 7.3 with 126000 miles. I just went and got a new alternator because mine is bad but I havent put it on yet. I have had my truck in 4wd all day due to snow and it is acting very strange. If it sits and idles for a few minutes or if I turn it off and turn it back on, it does this. When I hit the gas pedal it romps like it does when its cold, it has no power and wont even more. So I have to put it in neutral and rev the heck out of it for a little while. I then have to put it back in gear press the gas and after it romps some more like crazy it finally like catches and then will drive normally until it idles for a few minutes again. What does this sound like? Its never done it before and all of the sudden started and it just wont stop. Could this be because of the alternator? any help would be great .

I'm grasping at straws here, but I think you are losing HPOP pressure for some reason. I would find a scanner and monitor ICP and IPR readings, and check for codes. Or at least hook up a 3000psi gauge to the oil rail in one of the heads.

you need battery power for your engine to run, its electronic. maybe your batteries, or alternator wasnt putting out like it should,causing it not to run

Ya, if you are running on batteries alone its gonna run bad. But if it smoothes out occasionally then the HPOP sounds more likely. Sounds very coincidental bout the alternator though. I would double check your work and make sure all connections are tight and so on...
