My trip Odometer had words on it.

Ok,
so for the last week, my car acts like the battery is dead SOME of the time. sometimes I'll get in and its perfectly fine. then sometimes I'll start it and it almost doesn't turn over, but when it does... everything electronic in the car is reset. (trip odometer, clock, automatic windows etc). I kind of thought I had a ground somewhere or maybe a chaffed wire.
well today when i started it... it did it again and almost didnt start but I saw the word "fuse" pop up quickly and disappear where my trip odometer miles usually are. does that mean I have a fuse bad? wth does that mean? Is it code for "you have a fcked up electrical system" or what?
