2003 Ram 2500 5.7 Hemi throwing 0203, 0204, 0206 and 0441

Hey everyone. So I have a Ram 2500, no upgrades or anything like that other than exhaust (done before I got it). Gas powered 5.7L Hemi. The Check engine light came on and threw the following codes:

P0203: Injector Circuit / open cylinder 3
P0204: Injector Circuit / open cylinder 4
P0206: Injector Circuit / open cylinder 6
P0441: Evaporative Emission System Incorrect Purge Flow

The kicker is the truck is running fine with the codes showing and when I clear them out they stay off for about 50-100 miles before they come back on. No other issues (Other than the brake and ABS light on). Any ideas what might cause this?
