You're right that they have various different engine modes (Lando's Scenario 7 is the latest popular one given his last lap antics at Austria), I was responding to this:
Am I right in thinking their power fades quite heavily through the race too?
Which (in my mind at least) was referring to power loss due to wear (or similar) throughout the race.

I think it's definitely true that ultimate engine power decreases through the lifespan of the engine. The extent to which it does, and the cumulative of engine wear throughout multiple races, is one of those metrics which I gather is a closely-guarded secret, hence the use of older PUs in less power-dependent races. AIUI, one of the benefits of the now-outlawed Ferrari fuel-rate 'cheat' modes is that it allowed greater power without the engine performance degradation which you would normally expect with the usual 'party mode' settings by using a higher-than-permitted fuel rate to provide the extra power rathan than momentarily exceeding the PU's usual parameters. That said, that information is hearsay from a 'friend of a friend' source, so it could be total bollocks. I'm still not convinced it's not true though...

Yeah I was thinking over heating or seals wearing out or something.

Not sure that's really true. They definitely have an 'overtake' push to pass button and various different engine maps. And the famous Mercedes 'party mode' for Q1 quali sessions.
