did you recently change the fuel pump? If so you needed to change the wire harness thats attached to the fuel pump, then if not, your floater need to be replaced inside your fuel tank.
How do I know? from experience.

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Your tank sending unit is bad. Unfortunately, it is part of the fuel pump assembly, and the part costs around $400, give or take. plus installation labor. It is an all too common problem on GM vehicles, as I have had to change it on my last 2 GMs. If you do an internet search you will find plenty of others in the same boat!

Common problem on the 03-06 Silverado instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out.
