Since this is approximately ½of the phase 2 lifetime, you are probably
running into lifetime negotiation issues, or PFS issues.

I would turn up the debugging on racoon to get more information around
the time that the tunnel fails.

My hunch is that you have a PFS mismatch, so that the first tunnel
negotiates, but the second SA negotiation fails, then the third
succeeds, etc.
