2007.5 dodge ram 2500 6.7l

Hello i ran into a problem last night when i got home my truck decided it didn't want to turn off after i got home, I do not have a turbo timer. As far as performance/idle etc etc everything is perfect pulls like it should doesn't surge idles right at 700 as always. everything seems to be in working order except for when i go to turn the truck off it doesn't turn off, last night it finally turned off about a minute and 15 seconds after i removed the keys, I then restarted it and it took about 10 seconds of cranking for it to start then started up, I let it run for about 30 seconds to a minute and shut it off again, This time it took 2 minutes and 30 seconds for it to shut off again. I've looked online and can't find any forums about anyone having this issue, it does have egr/dpf delete.
