I have a 2001 grand am i was doing 60 down the freeway when the trac and engine light came on and the car speed dropped so I pulled to the side and turned of the car and waited for 10 minutes and started it again and ran fine for a day now the trac light comes on and the car feels like it has no power and shakes and dies let it sit for 10 minutes again and started it again and put it in park and accelarated the engine and the trac light when out for now does anybody know what could be wrong/ thanks
