1985 Nissan 300ZX non-turbo, will start and run at cruise speed for an hour and a half to 2 hours. Once stopped it will not want to start. The engine turns over but will not catch. After cooling for a half hour or so it will start with difficulty and run rough then idle at twice the normal idle rpm for 5 to 10 minutes before returning to normal. It's happened twice both on 60 degree days. The first time I thought maybe thinner air between sea level and 1500 feet. The second time was at sea level so no difference in air. Thanks for your help and suggestions.
