Cisco ASA 5505 IPSec tunnel won't establish until remote site attempts to connect

Question

I have a site to site IPSec tunnel setup and operational but periodically the remote site goes down, because of a somewhat reliable internet connection. The only way to get the tunnel to re-establish is to go to the remote site and simply issue a ping from a workstation on the remote network. We were having this same issue with a Cisco PIX 506E but decided to upgrade the hardware and see if that resolve the issue. It ran for well over a year and our assumtions was that the issue was resolved. I was looking in the direction of the security-association lifetime but if we power cycle the unit, I would expect that it would kill the SA but even after power cycling, the VPN does not come up automatically.
Any assistance would be appreciated.
