You need someone with a good scanner to scan the truck from what I can tell they are all voltage codes Have you tested battery and alternator/cleaned battery connections? Does the truck have any symptoms whats it doing?

thank you for respond . 1 yes two mechanic have good and professional scanner and said low voltage . they check everything and no one find where is the problem . i hope could sent video to see what happen . any way i have this truck for few month and used for hunting . no problem any where . last month i was 500 km out of city was first time happens . if engine is cold no problem after 30 minutes drive in city start to turn off with low speed . and power red light coming on . I should turn of the key and turn on is fine until i go slow in highway no problem when you push the gas run good if i can send short video i take 2 days ago is telling you all

I would re test alternator if you have a volt meter should be 13-14volts at battery when running also have the battery load tested and find a new mechanic if they where not able to figure a simple issue like this out..

i test alternator and charging is 12.7 and when is run is 14 plus

IIRC the Alt should put out 13.5-14.5 volts at idle not 12.7 volts
