Electrical issue

Definitely not a fuse. Except for the extremely rare corrosion on their terminals, fuses are never intermittent. When they blow, they're done and will never work again. You can have a stretched terminal in the fuse box cause intermittent problems. That results from someone shoving a wire or test probe into one and stretching it.

The most common cause of what you described is a loose battery wire connection. Be sure both battery terminals are clean and tight, then follow the smaller positive battery wire to the under-hood fuse box and be sure that connection is tight. Also follow the smaller negative wire to the body and be sure that one isn't rusty.
