Please expand...
The A/C never affected it.
For about a month, the climate controls haven't been changed; light fan, moderate heat on defrost. Seat heaters have been off, and I don't have the heat option on the steering wheel.

It should be in your instrument gauge settings, I can't recall the path exactly without looking at it, but if I was sitting in front of it, I could show you. Was the same with my '14 also.

Nope. It worked all summer with the A/C on and until this recent episode, it worked even with heat or defrost on. Had it on the entire time last night while the Auto Start/Stop was acting up intermittently. But when it's working properly and the truck shuts off at a stoplight, the fan, heat/AC does shut off. When you depress the throttle and the truck starts back up, the climate control also kicks back on.

It's not just cut and dry, there are different variables. The manual in the link on page 172 and 173 gives some of the variables and the A/C and defrost are some of them. I'm not saying that is definitely what's causing it but as others have said, many things affect it, or it could be as you suspect that something is wrong.
I’ll explain in more detail; this was just last night, after already driving for over 70 miles and I was just about back home. I intentionally continued driving around my neighborhood with the sole purpose to observe behavior, in a relatively controlled situation. In the course of over a dozen times of coming to a complete stop, the system only worked about 75% of the time. All of these particular stops were in a period of about ten minutes. In all of these stops, no input was changed. All stops during this time were on flat, asphalt surfaces with no change or variation in grade.
I intentionally made no adjustments or changes to the heat/defrost/fan settings. The transmission temperature stayed in the 180* range, and there was no noticeable change in engine temperature. No other switches, settings, or adjustments to any other systems were made. Nothing. I intentionally didn’t adjust anything at all; not the seats, interior or exterior lights, the radio volume, channels, sources, etc. No adjustments to the climate controls, change of shifter placement, no cruise control adjustments, mirror positions, wipers, mirror/back window defrost, nothing. And the outside temperature in that period, never fluctuated from 29*. The absolute only driver input was throttle position, brake pedal position, steering wheel movement, and the necessary turn signal indicator. Some of these stops were straight, some were left turns after stopping and some were right turns, probably an equal amount in each direction.
Ironically, the very last time I came to a stop, was as I pulled into my driveway. I hesitated putting the truck into park, and after about three seconds, the system shut the engine off. As I released the brake and pushed the accelerator, the engine resumed operation. In this brief “observation”, the Auto Stop/Start feature should have worked the same in all instances within that ten minute period. And at some point, it should have worked at least once, in the preceding two weeks, totaling about 700 miles when the outside temps were always above 50*, and everything else was in similar conditions.
Because of this focused observation last night, I’m convinced something within that system is not working consistenly. Not that it’s a huge issue, but I’m curious to know what’s causing it, and have it corrected.

After reviewing the owner’s manual on this specific feature, it does state that this sytem will NOt be enabled if the defroster is on, as some members mentioned earlier. I checked this on my truck, and confirmed that this is likely the issue. My truck’s Auto Start/Stop function is enabled while the windshield defrost is on, and it should be disabled. Apparently somewhere in the circuit, it reads confirmation that the defrost is off, and that’s likely where my issue is. After I take it for service of this, I’ll report back on what the dealer corrects. Thanks to everyone who offered their info.
