How to differentiate a Kodi crash vs a power problem

Hi all,

i am experiencing some quite non consistent crashes when i switch rapidly between live tv-channel. I do not see the rainbow square appearing so i ruled out that it could be a power problem but could it still be?
I have reported multiple threads on the kodi forums as well as on the github of the tvheadend addon of kodi with unfortunately no success. Other people have reported the same problem

I do think this problem is raspberry pi related and could be due to omx or mmal not handling the rapid switch of buffers because i can switch channel slowly but if i do it fast i might experience a crash but would like to rule out power drops. Is there a log which would tell me that i have experienced a drop of power resulting in a crash?
