It could be your injectors or your FICM. If you don't know how to Google search "test FICM" and check to see if it gets 45 volts or more when you start cold, at idle, and around 2,000 RPM.
Other things can cause hard start or rough idle as well. Do you have access to a scanner? Not one from auto zone ect. ..

its not the alt. it starts up fine its just right after it turns over and 5 seconds later it bogs down for about a few minutes then picks back up to idle

If you can squeeze it I would get a scan Gauge II and keep it in the truck to monitor FICM, Batteries, Alt, and a bunch of sensers. you can get T-6 Rottella or Delo at walmart even the OEM oil Filter too and change the oil your self ( Note don't use aftermarket oil filters and cap) not even for Fuel
what weight Oil and did you get OEM filters?

Use only OEM filters and get a monitoring system. Torque Pro app for Android costs $5 and an OBD II adapter runs about $25 through Amazon. Dashboss for Apple is about the same as Scanguage but does quite a bit more.
