Audio issue with The Walking dead and Onkyo Receiver

[jcmountain34]

I have a PS3 Slim sending audio via bitstream to a onkyo receiver via HDMI. I am trying to watch the walking dead season 2 disc 3 and 4. During the last episode on disc 3 the receiver will click off and stop playing. The PS3 will continue playing the disc but the receiver will stop playing sound and turn off and the red power button light will blink. It also does it on the last episode on disc 4. I have exchanged the set and it still does it. I will turn the receiver back on and and it will play for a little and click off again. After it gets past a certain point though it continues to play without issue. I was wondering if anyone knows what would be causing this issue.
