Looks to me like you've MIGHT have a FICM going for a poop.
I would look closely at the pinpoint test for the P1378 first, as it can cause the P0611 and the P0284 to set.
Check all the FICM power pids, see what they are reading. The 1378 sets when the FICM doesn't get voltage from the battery to build the 48V required to drive the fuel injectors which is the P0611 code. So now you will get misfires, hard/no starts, etc.
It's a big circle, viscious cycle type of thing.
