I have a 2003 saturn vue the car will run for about 15 to 20 mins then stop if you let it sit for 20 to 30 min it starts back up again and the cyle starts over again the motor is a 3.0 liter, my scan tool has a trouble sec it said to check the connection on the fuse box for f-12 that conrols the ign fuse.I removed that connection and recrimped it to make it tighter I also cleaned a ground spot located under the drivers side head light no luck yet, I had a crank code when I first scanned it but I thought I was just getting that because the car keeps shutting down and then is trying to be restarted any help would be great oh I dont have any rpm single after it dies thanks Bill

Please post the exact code numbers not the code descriptions it sounds like a bad crank sensor though pretty common for that engine when the sensors go bad they fail when they get hot usually. Do you have a multimeter to do some testing?

Alright run it till it gets hot and wont start and unplug the crank sensor and check between where the purple/white wire goes to the sensor and the white/black wire goes it the crank sensor and your going to be checking the crank sensor harness the one that goes to the sensor. You should 800-1200 ohms or you have a bad sensor let me know what you find.
