Yeah..although I have not had that I have found some connectors that fit loose enough to cause a poor connection...enough to make heat and if it can do that, it can blow a fuse. It also can be something pulling too many amps like a bad starter solenoid or just a bad connection on it. Like Cosmo says...the hunt is on. Fortunately you know it's on that circuit that blows that same fuse....and you know its starter activation-related so..shouldn't be too bad. Start at the solenoid and work back.
