Sound bar quits playing after about a minute

I have a polk 2000 sound bar, directly connected to my tv with the optical cable. Powers on and plays for about a minute or less and the power on light begins to flash amber. I've tried every power supply I have think that may be the problem but same result. What am I doing wrong,
Thank for any help.
