i had just bought my rx8 its a 2004 with 129,000 runs great no power issues at all no funny noises, nothing. comes with a stack of mantinence paperwork. ill drive for however long it could be 2 hours or 15 minutes an ill shut off car an it strugges turning so i have to wait about 15 min for it to start. any idea what the problem is? some ppl say coils, some say starter? an the rare few say motor but it runs flawless when its on. please help i would apreciate it

 

I am having the same issue. I have a 2004 with 89,000 and mine does the same thing. I changed the spark plugs and wires but that didnt help. I took it to the dealer to do the compression test and everything was good. I am buying a new starter next because thats about the last thing on the list. So most likley it is your starter if you have the old one.
