2024 Bronco 2.3 Auto Died

[2021FordBronco2]

I was driving my Bronco and while slowing down for a bump in a neighborhood my Bronco died and showed this message, auto start stop is off, anybody know what it could be? Vehicle did feel a bit down on power in lower rpms and was a 100 degree day. Maybe @Ducati1098 can help me out?

Hard to tell from the message, but I believe it wants you to uninstall the slushbox and put in a manual.

If it was a bump, check your battery cable.
If it was a pothole, it was a wheel speed difference.
It's not a thing right now and probably won't be later. It's just a factor of things warped and moved in a specific hard to duplicate manner...ir your battery terminal is loose.
Have a dealer tell you.

Battery cables were good, wasn't a pothole either, I was going maybe 5 mph over the bump, the bump is just a gutter for rain at a crossroad, my trans has been shifting funny lately so I'm wondering if its that

That was the initial error I got when the fuel pump on my 2022 2.7L went bad. It only 3022 miles on it and it was a 100+ degree day on a bumpy dirt & gravel road in the Nevada outback.

That is good to know, thank you for your help!

Did it restart?

Of course you should report these to your Ford dealer and have them take a look, but your issue seems oddly familiar.
I mean this is just speculation, but I am having a very similar issue with my F-150. At very slow speeds, usually I'm on the brake slowing for a light or something, like 5mph, sometimes the engine just stalls for no apparent reason. This does seem to happen during hot weather, and has occurred about 10-12 times to me so far. The number of potential causes are a lot: faulty brake position sensor, low pressure fuel pump failure, fuel injector pump failure, the list goes on. My dealer says they have not been able to isolate the root cause, but I suspect one of the fuel pumps is beginning to fail and there is a massive F-150 recall for this problem, for which Ford has agreed to fix, but not found a solution for in over a year. Shift into park, restart engine, move on, at least for now is I all I can recommend. I will say that fortunately I have not had this happen at any significant speed, at least not yet. My plan is to get a Forscan compatible cable and see if I can at least read the DTCs myself to perhaps give me some idea of what's going on. Ford not forthcoming, at least yet.

Send me your VIN and I can check for codes. That’ll be the best indicator of what happened

That's what I was thinking: the low-pressure fuel pump. That would happen with a manual transmission as well (without the message). I think there was a recall or service note on that. Notably: the problem is most apparent with high heat, and is likely tied to addressing vapor lock.
