Recently my 2008 Tahoe, turns off while I’m driving. I pull over and there’s no crank over, no click on the ignition. I wait give it about 5-10 minutes then it cranks over starts and gets me home depending how I am. The battery is good, and recently I replaced the alternator since it took a crap on me, the little battery light turned on, on my instrument cluster. Definitely need help resolving this issue.
Need help with Tahoe shutting off?

This sounds like an electrical issue if the symptom is similar to when you have an alternator die and the truck stalls after the battery is drained. Have you checked your ground connections and inspected the wiring? I would suspect you are getting intermittent power supply.
All the grounds or engine ground?
I would focus on the negative cable ground to the block, as well as the ground wire coming off the back of the cylinder head to the firewall. If your cables are original, I would replace both positive and negative. (For at least check the cables for resistance)
I would also pull up to pretty much any auto parts store and ask them to load test the battery on the vehicle, as well as test the alternator output on the vehicle. I think AutoZone still does that. It wouldn't be the first time someone bought it defective new or rebuilt alternator..... And sometimes batteries just go bad, regardless of age.

Ok so I let the truck run at my house, ran for almost 30 minutes turned off. I turn the key off went to the fuse box, I heard the run/crank relay click and the truck started up.
It started up with the key turned off?
My bad, I heard the run/crank relay click went back to the ignition key turned it over and it started right up.
Yeah forgot to mention that I actually went back to the inside and turned the key over. But yeah heard the relay click went back turned the key over and started.
