erroe codes p0204 and p2046

Driving hoem yesterday the truck started "stuttering". Next minute check engine light flashes and stays on. Got the truck to napa to read the codes. Got the above mentioned. Cleared them and drove home, no problem. This morning on the way to the dealer, it happened again, they got the same codes.

I had the injectors replace less than 2000 miles ago.
Got a call from the dealer saying it might be a wiring harness?

Does anybody have any experiecne with this?
I know the p0204 is disconnect injector, but not sure about the other code.
