codes p0603 and p1316

I have an 2003 f350 7.3 and was driving along and truck just starting losing power, like running on half of all cylinders. Put it on a scan tool and it kicked out 2 codes 0603 and 1316 respectively. Question, why all of a sudden and what would cause these issues? Thank you in advance.

P0603 KAM Memory Loss
P1316 Injector Circuit/IDM Codes Detected
The first code usually set if the battery is disconnected. The second speaks for itself.
Check all the wiring going to the injectors, leading into the valve covers, etc. You may just have a loose connection somewhere.
