2003 Saturn Vue

Electrical problem
2003 Saturn Vue 6 cyl All Wheel Drive Automatic 58000 miles

I have a 2003 Saturn Vue 2-wheel drive 6-cylinder vehicle. One day I was driving down the road and all of a sudden she noticed the instrument panel gauges give out (RPM, Speedometer, etc) and went to zero. My power steering also failed when I turned the car off then back on. Now when I start it in the moring when it is cold out, the promlum is gone. But when it is warm out the car starts whit the same trouble, the check engine light, check engine soon light, brake and the ABS lights all come on and stay on with no power steering. When it is cold out there is no trouble. Is there a sensor or computer chip that is controlling all of these electrical devices posably under the dash or some where effected by tempature. I'm a single dad of 3 so $ is tight all the time so I just can't take it in. Your help will be greatly appreciated. Thank you

Did you find out what was causing this, because I have the same problem and Saturn tells me that nothing is wrong, if upon restart all the lights go off, supposedly indicates no problem. Something is definetely wrong, as this has now happened 5x, the last time not having power sterring was more then a little scary in the situation I was in.
