2000 LeSabre died at 65mph
Hello, I'm Steve. I have a 2000 Buick LeSabre. Since I bought the car, I replaced the fuel pump and cat converter. Last summer, nite time, the motor died on freeway. Coasted to a stop. An hour later it restarted. 5 min. later died again. This is it's pattern ever since. It will start and run fine until the thermostat gauge starts to rise. When it's almost to normal temp, the car dies and won't start again until it cools off. No codes. I've read here about icm, and crank and cam sensors. Any info you could give me would be appreciated.
