My coupe has been doing the same thing for about 3 months now, My battery is in the trunk, so I don't think it is the battery getting hot. It starts fast as hell in the mornings and after work, but if I kill it for a short time and start again while she's still warm it's very slow. I was told the mini high torque starter sloves this problem and will be getting one next month if the wife allows. It is very common to have this problem with long tube headers, the starter gets to hot and starts to act up, the mini starter again will fix this. Good luck to all. I will let everyone know how the starting woes develope after the starter is installed.
