Hey, I got some info that really helped me out. First off I figured out that the radio lost it's memory when I started it, never when I just shut it off and turn it back on. Someone gave me some info about the battery possibly being low enough that while starting, the battery voltage could be drawn down low enough to kill power to the memory circuit. I checked it out and did notice that the car had been lagging a little at start-up. Not real noticeable though. I checked the battery connections and they were good. I had the battery checked, it was low so I replaced it. Better starting and the problem solved! Check the battery!
