02 Suburban factory cd radio. It cuts off and resets. Sometimes it stays on for an hour. sometimes it does it every few minutes. it is really aggravating and I dont know what is causing it. I know it didnt do it before i started using my Scanguage II. But it started after several days of plugging the SGII in. Is there any one else that has had this happen and what should I look for?

 

check the main ground lug on the frame at theLF of the truck. It is the main body ground and is notorious for having a poor connection
