HELP!! 8 OBD2 codes. No idea where to start
 

Ok, I'm new to this diesel world. Have an 03 power stroke 6.0 that runs for about 30sec and shuts off. Restarts immediately and does it again and again. Resists taking throttle initially but the revs up only to like stall out and steadily lose power. Then dies again and will restart immediately. Thought it was a fuel issue, drained HFCM and it was bone dry. New fuel filters, no better. Friend ran codes and found 8 OBD2 codes listed below. I don't know what these are or where to start. Please help.

B1317
B1318
B1352
U1027
U1051
U1073
U1147
U1262

I'm lost!

B1352 is the KEY IN Chime, the annoying noise when key is in and you open the door.

Check you main wiring harness on the drivers side of the engine bay, make sure all the connectors are clicked in all the way, there are several connector. also make sure where it comes out of the fire wall is all good to. you are having communication errors, also check the fan switch connector at the top of the fan housing because if those wires get cut it can cause problems too

Your right! Just tested batteries. Running about 65%. May not fix that door chime unless I gotta. I'll check the connectors next on the DS and on the fan and firewall. Thank you for the leads!

Ok, all connectors on Driver side look good and are making good contact. Firewall connections also. Batteries on charger. Still got the same issues.
