Law of conservation of energy says that energy can't be created/destroyed, so it's a finite amount. But the universe is expanding infinitely, so is energy becoming relatively more uncommon? Matter as well? Will the universe eventually expand to the point that it can no longer support anything because all energy and matter will be so far spread that it's never able to form anything?
There may be an easy answer to quickly end this, but curious to what other people thought/know.

No one can "know" the future of the universe, or even its past. We can only view the present and make predictions ( best guesses? ) as to the future.
However the situation you describe is well known in modelling of animal populations.
When the density of the population becomes too low the probability of finding a mate becomes too low and the population is headed for extinction.
By concentrating the limited population in an appropriate area we INCREASE the probability of successful breeding.
So IF the universe did expand indefinitely then your explanation would be valid.
The energy density ( which also represents average temperature) would decrease. And the probability of recycling matter in aggregates of stars or planets would reduce.
Eventually there would be a very low probability of this occurring.
But note the word IF.
Even if the universe is expanding at the moment that doesn't mean that it will expand for ever.
It MIGHT mean that. But there are other scenarios.

your theory seems solid, and has been visited by top scientists before
it is theorized that the universe will keep expanding infinately, or expand to a point then stop, or expand then retract (ending in the big crunch) it is thought however that (rather than energy and mass levels as you say) effecting this, it is the contradicting levels of dark and anti-matter (long, complex story behind them - if u want them explaining, im happy to help out there)
hope this helped :)

The expansion of space has relatively little to do with the occurrence of energy. Since universe is technically space, matter expands along with it. Hence, the separation of galaxies.
Technically, the universe is not forming new energy. The energy keeps getting recycled into cycles. So does the matter. Thats why dust and particles end up being asteroids/comets while some supernova's ignite concentration of hydrogen/helium into stars.
