You changed which fuse? If it's not a coincidence, with your history, you have to Really take a good look at what's going on in your fusebox, there could be all Kinds of issues from that alone!
What scanner are you trying to use (Most won't properly pull codes from our trucks) and this doesn't sound like an issue that would generate a code to me...
Here's what ya got, the KEY cylinder sends a signal to the relay in the fusebox Thru the NSSW (or clutch sw in a standard) to close it's contacts and enable the solenoid on the starter itself to throw the Bendix, engaging it's gear in the flywheel and turn the starter motor.
So, wiggle the Key / move the shift selector to different positions / wiggle the relay / take a hammer and Rap on the starter motor / go over the starters connections.
ANY one of these components can be bad, your problem is intermittent so, hopefully, by trying each one you can determine what the bad one is......
