Question
my car has an after market stereo put in 7 weeks ago...about 6 weeks ago,it started shutting off as i was going down the interstate..i would lose power and it would come back on..i noticed that it only shuts off when i turn the radio on...i have drove it problem free when i have the radio off..but if i turn it on, the car will run a while then shut off as described..im going nuts..i have had it checked at radio shack and they said it is hooked up right..they said if they had put it in,they would have done it the same way its installed now..so i cant figure this out.the factory radio is plugged in now and i dont have code..any suggestions? need help bad

Answer
Hi Christopher

You may ant to take it to a saturn dealer and have them diagnose it, I have never run across that in my time with Saturn........I wish I could have helped more, but without accually looking at the wiring ect. I just would be able to tell...........

sorry
