So we have what we want and knows the problem.
There is nothing we can do to prevent fuses from blowing as they are meant to blow when something is wrong and it could be due to overheating or it could mean something is on its way out and it would happen again.
Since it supplies power to the various relays and ignition switch, any one of it could be failing causing the problem. If it is a one off, then it could be due to overheating and over long periods of time, it fails. The only thing you can do is to check the fuse for signs of overheating and if there are any, replacing the fuse as a precaution would help.
