Echo turns off after 90 minutes

[ChrisTheodore]

Hope someone here can help me as Amazon Support is clueless on this issue;

I have an Echo and Echo Dot.  If I say 'Alexa play Spa Radio on Pandora' - it tunes in and works fine but after 90 minutes Echo turns off but itself.

Yesterday Amazon pushed down a sftwr update to the Echo Dot and it seemed to clear up the problem but today when I tuned into the same station and was away for 3+ hours it (Echo) was off when I returned. 

Anyone else experiencing this issue with Dot of Echo?

Thanks,

Chris

Disconnect the Echo for 5 minutes.  See if this clears up your issue.

How do you know this?
