So in "Darkblade" (which was an audio error) and "The Pharaoh" (which was not), Cat Noir's ring beeps without him actually using Cataclysm (a second time, in the case of "The Pharaoh). So, even without using Cataclysm (and presumably Lucky Charm), Ladybug and Cat Noir can evidently run out of energy and detransform without doing anything. I would hazard a guess this happens when the kwami doesn't get sufficient snackage beforehand. Sufficient sustinence? When it doesn't eat enough to have the energy to maintain the transformation for long. Having a timer on them might be because the Ladybug and Black Cat Miraculouses are the most powerful ones, since there doesn't seem to be a way for the other five to have them. I don't think the other five have the 5-minute timer-triggering moves, or even timers at all, considering we've never seen such a timer on either Volpina (who may or may not have been using the powers of the Fox Miraculous) or especially Hawk Moth (who is in every episode and has had ample time to show us if he has such a move).
The others don't have five distinct things on them like those two Miraculouses- Hawk Moth's locket has four wings and the locket itself doesn't have any distinct markings on it when transformed, there are nine peacock feathers on the Peacock Brooch, the Fox Necklace doesn't actually have any stripes on it like it sometimes does in "Volpina" and has two parts on it in the colours on it (but there are six segments on Volpina's necklace when it does have them), the Bee Comb has seven stripe on it (eight if you count the head) and four wings, and there are six triangular markings on the Turtle bracelet. There's no indicator that they have five-minute timers, since none of them have five markings on them. The only one you could stretch to say has five markings on it is the Bee Comb, if you use the four wings and the head, but the other four have nothing like that. So there's probably not timers on them, considering the Fox can only be stretched to have two possible minutes if you take the fact that it has an orange part and a white part on it, and that it being in segments is not supposed to be a thing since when they show the Miraculous in the book and in the Box, it doesn't have them.
So looking at the Miraculouses in the chest (where the kwamis are inside them, so that's what they look like transformed), it's safe to deduce that the other five don't have some special move (especially if you look at how powerful Volpina and moreso Hawk Moth are without using one). Nor, by extension, do they have timers. So can their kwamis run out of energy? Or do they get no warning from their Miraculous before they detransform?
Kinda late, but. You yourself already said that Ladybug and Chat Noir can run out of energy without using Lucky Charm and Cataclysm, so most likely so can all the others, else the strongest miraculouses ever would just kinda go down hill and make things more unbalanced (Again as you already said Hawk Moth and Volpina; Although with Volpina we do not actually know if it has the same powers as the real one; are extremely strong), plus there would be no reason for their respective Kwami to never be hungry nor needing food. And about the warning... I have no idea I mean... The bleeping thing could still go off but have no physical indication I guess..?

Well, that's the thing I find so peculiar- Ladybug and Cat Noir don't seem to stand out except for their five-minute timer moves. They're not all that impressive in the end. I think it's possible we have not seen nor heard the full extent of the Black Cat and the Ladybug's powers. They also may be the only ones that are flexible enough to use the Pearls and adapt to their surroundings, because they're Yin and Yang, where the others are likely in more rigid positioning. There's a few people who talk a lot about the Miraculouses representing Wu Xing, with the Peacock being Water, the Turtle being Metal, the Bee being Earth, the Fox being Fire, and the Moth being Wood, so they'd be less flexible to adapting than the Yin and Yang ones. My only problem with the theory is how far some guessers take it to become very literal and how people use it to say the Bee is a healer (because a healer is pointless if you don't take damage). I agree they probably do represent the different elements, why else would there be five, but in a represent kind of way like their powers relate to what the element represents, not a literal "the Peacock is a water bender" kind of way.
So it's possible that's part of what makes them so overtly powerful, but I think we have not yet seen their full power yet, but we have seen the extent of the Moth's.
