Whit the debug log activate try to use the addons......... watch the cpu load % or similar value... for example the memory usage or similar. If you obtain high value it's problably the cause....... the addons it's to heavy for your setup.

Are you tryed to change the PSU ? You obtain this only whit youtube addons or it's happen also whit other ? 

only with youtube addon, and only after 5.5.1 update
previous version before "Signature deciphering fix" worked without any problems.. 
other video addons (eg twitch, iptv simple client) work fine, same as before 

 Try to post the debug........ but i don't thinks it's usefull.



Meantime on my Pi2 i can't reproduce this video:
