Mine's a 2002 S2000 with 32,xxx miles. Everything about the car is mint, except this weird behaviour.

However... today I found this link: MAP WHACK!!

I performed this during my lunch break.
Reset ECU and everything.
Let's see how it goes. Will update.

In the meantime, I ordered the new part#06176-PCX-000 MAP sensor to a local Honda dealership. If the issue comes back in the next few days, I'll pickup the new MAP sensor ($65) and try that.

if you think it may be heat soak, take the hood off lol

Heat soak exacerbates the issue. A map whack will do the trick. Think Aflac and say MAP WHACK!
hehe
GL!
