Hi Uzair,
It should automatically connect back as soon as the ASA fails over to the standby.
You should connect the syslogs on the ASA whenever this happens.
I understand you want to also reduce times associated with failover during interface failure
on ASAs. This can be achieved by reducing the poll time and hold time for
interface using the commands mentioned here:

tive_standby.html#wp1116389
Specifically, the command you need to edit is the failover polltime
interface command. Please note that keeping the values really low can lead
to false failovers at times.
You can read more about the interface testing procedure here:
