I have a 95 m3 3.0l that every time the car get warm or a running temp for a while in the heat only. The car will lose power and die. Then throws codes c9 for lambda control #1 and 09 for o2 sensor. And will not restart till it's cooled off but once it's has everything is back to normal and runs fine. Help please.

I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume, quality and engine compression. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.
