Default 2015 Suburban transmission issue

Hey guys, just recently started having an issue with my transmission and was hoping someone might be able to help me diagnose the issue. Everything works fine until I come to a stop, then nothing. No forward gears and no reverse. If I shut off the engine and restart it I get the gears back until the next time I stop. I'm hoping it could be a control module or something electrical so I won't have to replace the transmission. Has anyone had similar issue?

Full code scan of the truck is needed. All 4 code families not just the P codes is step one to help find a direction to proceed in.
