May I ask a question please?
What type of creature, large or small, could sustain it's population by feeding only on it's dead plus air water and sun? Living creature, but not plant life.
I'm researching for my science fiction novel, so this is important to me.

To my knowledge, none. This would not make any evolutionary sense. There are many animals which will cannibalise for short periods of time in the absence of other food or to kill the offspring of a potential mate. For example, many species of toads, crocodiles, insects, dogs...even our beloved dolphins have been known to have a taste for the flesh of their own.

Maybe it could work with a, made-up, species of some sort. They survive off of each other. Maybe a bug. Bugs reproduce in huge numbers so maybe they could eat their dead with enough to still survive. The species could would have to reproduce very quickly too to keep the numbers up. Good luck with the novel my favorites are science fiction.
