Virgin Media 5 Router power lights going off and losing broadband regularly.

[Ekflyer]

Anyone help with ideas?

My router seems to be losing broadband connection regularly and it looks like its powering down?

Switch it off, wait, on again it connects for a little while then does the same again..

I've previously reset it, works a while then does the same...

Here's what's on my logs:
