Your VPN's disconnect automatically because they don't hear anything from each other. It's like they are not talking to each other so each ASA believes the other is dead. In order to fix this you use DPD(dead peer detection).
What DPD does is to send keepalives to each other the default on ASA is 10 seconds by default. You can change that if you want but its not recommended. So, in this way both the devices know each other and keep the tunnel up and dont tear it down.
