This is a weird one. Hopefully someone has seen it and can diagnose.
I will be cruising along fine and then the radio goes silent (I know it still has reception because I can still see the title of what I am listening to on the display). Shortly after the sound goes away the engine shuts off. Sometimes this happens long enough that I have to pull over and restart, other times it starts right back up and I just lose a few MPH. This has happened about 6 times now. Each time the seat memory is gone, but the radio stations remain. One time the service power steering light came stayed on for about 10 minutes but then went away. I took it to the dealership but they said they couldn't diagnose unless it did it while they were driving. Of course it didn't. Someone please help!

 

Forgot to mention the vehicle is a 2009 RL

 

Check your battery cable connections. They should be snug - to the point they don't move if you try to move them by hand. If one is loose and can't be tightened any more, put a screw or nail between the terminal and connector closest to the nut until you can replace the connector.

 

Thanks for the reply. The battery connections are good

 

You should get your alternator tested.
