I have a 2006 cummins 2500, smarty, volant cai, and no muffler other than that its stock. It will start just fine plugged in or not but after idling for 5 to 7 minutes it will just shut off like you shut the key off and it would throw the code p 2509 but yet start right back up. first thing i did was cleaned grounds and battery conections, it still did it, i went and bought brand new batterys, it still did it. then i updated my smarty to the newest software and now it still dies but doesnt throw any codes. when it first started getting cold out this fall is when i started having this problem. the truck runs just fine over 25F and dies more and more the colder it is outside. ive been running straight #2 so i thought it was maybe the fca but i havnt done it yet. If anyone can help thank you before hand.
forgot to mention it also the electronics all shut off while driving down the road but they kick back on after a second
