red lines it when he drives it - why is it with this car once it warms up and you
drive to say maybe get gas - it won't start up when you get back in it -
what kind of diagnosis can you suggest?  the Mazda dealer thinks I'm stupid

Inherent design problems everyone knows the Mazda RX8s were a major fail the Wankel (rotary) design was dropped years ago because of all the issues the Mazda dealer knows all too well! Floods out unless run till heated, burns as much oil as fuel etc..etc.. these were novelty cars. Plenty of online info.

Great cars, but engine design was lacking. I have often wondered how many engines Mazda has had to replace under warranty over the years. I'll bet it is thousands. Run a current draw test on the starter. It may be drawing too many amps to turn over when warm. Also check the connections at the starter and battery. These connections must be absolutely clean and free from corrosion.

Low compression.

I had this exact problem at less than 135k miles. Guru 1Y61 is correct: Low compression. I just noticed that this thread is from a year ago, so you've probably replaced or had your engine rebuilt.
