IPsec VPN disconnects but still says it's online

I am having an issue with my IPsec VPN disconnecting (traffic no llonger travles across it, testing with pings) it lasts for anywhere vetween 30 minutes to a few hours and then disconnects, however if I go to the VPN> Connection status it says it is connected, "IPsec SA Established"

I had been doing some testing with setting up AD integration with users and trying to get the VPN lite client set up and then opening ports for windows VPN via IPsec to try and get a user set up with a software VPN connection to the server however I was carefull to not touch any of the site-to-site VPN settings and I went back through and removed all the settings I had changed, other than a new PPTP port forward to the server and now every once in a while it just drops, only way I have found to re-establish the connection is to reboot the Firewall, here is the last log I got from the last time it dropped:
