2004 Suburban 5.3 4x4 non-operational

I am perplexed. I had a 2004 Suburban that functioned exceptionally well until recently. Upon turning a bend, the vehicle experienced a loss of power and ceased functioning. Inserted a fresh battery, still there was no response. New alternator; audible bearing noise, no other issues. The cables seem to be in satisfactory condition, and the starter has been tested successfully. Have not attempted to initiate it. What have I overlooked? Replaced the starting relay, nevertheless the issue persists: a single click occurs, followed by behavior indicative of a dead battery. Your insights would be much valued!

You are indicating that when turning the key, there is a click, but the starting motor does not engage. Although the starter may test positively, it might still be defective; nevertheless, this would not explain your truck's failure while in motion.
What do you mean by "haven't attempted to initiate it"? What do the gauges indicate when the key is turned on?

Apologies for the oversight.I hear a solitary click that seems to originate from the starting area. Uncertain on the origin of the other component.I am now at work using my phone for this task.

The gauges indicate normal readings. Upon attempting to restart it, it emits a clicking sound and thereafter behaves as if the battery is depleting.

Consider having an assistant maintain the key in the start position while you strike the starter with a hammer. When it is time for a fresh beginning

I suspected the starter, which is why I removed it and had it tested at AutoZone. The reliability of a bench test is questionable due to the absence of a load.
