Hello guys. I have a 2000 acura 3.2 tl we run circle track with. It recently developed a problem. When were racing and the temperature gets up to center or a little pass the engine shuts off like you turn the key off. But you can cycle the key off and on and it will start right back up and run fine. I replaced fuel pump but it still does it. What could my issue be? Im figuring a sensor of some sort. And sometimes when you restart car it has rough idle. U can shut it off start it right back and car idles perfect. Doesnt make any sense to me. Any help would be appreciated
