Every once and a while the radio would shut off and turn back on.
Yesterday it just shut off and now only the clock is flashing.
I checked all fuses and there ok .
Any suggestions?

 

I know my truck is a 2007 but I am dealing with a similar problem as well. My radio does the same as yours but the clock has also been staying on when the truck is off and the doors are open. I think this is the reason for my dead battery. My problem usually happens after it rains or when the snow melts. I think water from the 3rd brake light leak is causing my problem. If you use the search function there's a lot of posts about electrical problems. Some are also caused by a corroded wire on the driver side under the plastic trim that runs along the cab. Hope this helps and welcome to the site

 

Johnny it sounds like your issue is being caused by a bad radio itself, which is probably out of warranty by now. I have the same year XLT Screw that I'm upgrading to an Alpine aftermarket this week, so let me know if you're interested in my oem radio.

Miller, I had a similar issue with my 2005, and after troubleshooting the door switch, harness, wiring and radio, I found the problem in a faulty ECM module. Once that was replaced, everything went back to normal.

 

Mine is doing the same thing right now and I just replaced the radio about 2 years ago was under warranty and now its doing it again usually it comes back on after I turn ignition off and then back on but now wont work at all.
