Help!...Need help with a 2011 Freightliner Cascadia DD15!

Thank you so much for the pdf link, here I will try to upload you some pics from the previous codes when it first started showing this problem. intermittent first with days in interval before showed again, until it was constant as soon as I turned the ignition on, then all injectors were replaced then started showing different message or codes which are the last pics uploaded here, and they will come on after driving sometimes for a few minutes or couple of hours, still same problem after injectors, alternator and ECM were replaced, going crazy here, unfortunately I know nothing about mechanical repairs, and believe it or not this truck has swallowed almost $20,000 in repairs, all my money is gone now, which took me to believe the dealers instead of fixing this truck they have created more and overcharged me dearly, but I'm still have a little hope that we can finally fix it specially with the help of people like you guys that without any reward have put their time and knowledge in trying to help me and again I thank you all for that.

 

Hello, sorry to bother you again, here are the codes that it has showed since problem started, Thank you.

 

Hello, the first code ever which is not showing anymore is SPN004259 04, then the ones showing now: SPN000651 and SPN000653, Thank you so much.

 

I'm in Las Vegas and the truck is in this small shop here called Diesel Tech, Inc., I will pass all this valued information that you gave me to them but I'm also willing to bring my truck to your shop if they are unable to fix it, actually I drove it last time it broke with a load from Buttonwillow, CA to Las Vegas, Thanks again.
