I have been having this problem on and off but it just got worse today.

The radio will just turn itself off and then come back on. This time I’m going down the expressway and all the sudden I feel the car hesitate for just a split second and at the same time the radio, traction control and heated seats turn off and the low tire pressure light comes on. Then the radio comes back on and the tire pressure light goes off. Has anyone else had this problem? I have a 2005 SRT6. It is out of warranty so the dealer won't be fixing it.

Thanks for any help anyone can give.
