It's the number 1 thing that pisses me off. Just give a straight answer and then kick OP's butt for not using the search, because that actually helps the next person who actually searches. If you don't use the search, you're a noob, and if a user only posts to say that OP has to use the search, he's twice the noob.
These stickied posts are also just a big mess. Why not just make a wiki-page for RX8Club where everything is sorted nicely? Never have I had a problem with finding something on Wikipedia which can be edited by any community member instead of just one know-it-all who has left the forum months ago.
OP: Call the dealer, get a compression test done. The tests are inexpensive and will give you a straight answer. Don't look for any more symptoms in the hopes it's one that you don't have and therefore convincing yourself that your engine doesn't suffer compression loss.

Tom, your post was so wasteful that it barely deserves a response.
The only reason I'm responding is to point out the fact that you replied to a person who made the OP 5 years ago. And many times did people respond with signs of low compression to go get a compression test. That is all across the forum, and not held hostage in this thread. But thanks for thinking you're a light bulb in a dark room...
Search works if you possess even a minute amount of patience. But people like you are so used to instant gratification that you can't function without it. I call it "spoiled".
The stickies have plenty of info that is valuable. If you want to create a wiki page, feel free to do so. We won't miss you here.

If the car is idling fine, then I'm assuming its not dying on you at stop signals or so.
There is one issue that popped up recently with a friend's RX8...and it started exactly like your problem... with hot starts. After the hot starting, the car started vibrating, was unable to hold idle and was making pinging noises at high revs. Plugs and coils were fine, so this all sounded like the engine failing. However upon the suggestion of another friend, he changed the fuel and it all went away. The car started running like new again... compression was also tested later and it was fine. He also started premixing after this and says his car is running better than before.
If you've changed your fuel recently, you might want to look into changing back.

You will have more luck if you are very descriptive of what is happening...and start your own thread...and stick to it when you are getting help
Chasing you all over the forum and finding different descriptions about what is happening is a real PIA

The idle is fine, no problems there, regardless of temp.
Plugs, coils, wires were just replaced a few thousand miles ago so the issue isnt there either
Like i said, the only problem ive noticed is the hard starts when the engine is hot. It makes me wince every time i start the car when hot and it takes so long to do so. My poor engine...

Multiple choice:
A) who lives in a pineapple under the sea?
B) SEARCH NOOB
C) difficulty starting, difficulty idling, stalling at idle, slight power loss
D) low compression values when THE ENGINE IS ACTUALLY TESTED FOR COMPRESSION
E) Both C and D
