2012 Yukon Denali 6.2 engine shutoff while driving?

[testdepth]

This truck engine shutoff once while driving down the road 2wks ago. This week it shut off a second time when my wife went down the road and stopped at the stop sign. Both times she shifted to park and it immediately restarted and ran fine. No issues starting or running other than these two times. No check engine light or engine codes thrown.

Any ideas.
