Engine shut down

[Kwalk1959]

Yesterday I was traveling 50 mph and the truck felt like it shut off and turned back on. Anyone had this happen? Hasn’t done it since.
Also what is all that noise in the engine compartment when I turn the truck off??

Wow, that's a bit concerning. Similar feeling to the auto start/stop I'm assuming?

As far as the engine noise, this might help:

3.0 noises after shut down.

Noises after shut down. Is this really normal? https://youtube.com/shorts/z-PBLN1h0IQ
