Hi,
The issue could be the fuel level sensor, but there could be other causes as well. Since the level sensor is in the fuel tank and not easily accessible, I would recommend having the computer scanned to identify any diagnostic trouble codes that could point us in the direction of the cause. If you look at the pic I attached, it shows different codes related to a malfunctioning fuel gauge.
Here is a quick video showing how a scan tool is used:

I realize most people don't own a scan tool, but often times a parts store will do it free of charge. I would start with that.
Let me know what you find or if you have other questions.
Take care,
Joe
