Hay guys I have 2014 2500, last night I took it out and it started a Regen with the exhaust brake on and when I came to a stop at a light it idled up a little and then it stalled no lights. Restarted the truck and at the next light it did it again, when I got to my buddy’s house I held the brake and it was about to stall again. It doesn’t seem to stall without the exhaust brake.

Any help would be appropriated.
