SOURCE: fuel gauge problem
The nature of the gauge is that it should behave with a linear taper between full and empty. If it works when full but then malfunctions as the level drops, the variable resistor in the sending unit which is housed along with the fuel pump in the gas tank is almost certainly at fault. The sending unit will have to be replaced to fix the problem. Expect this to be an expensive endeavor.

if the fuel pump is all in-tank; the sending unit built in to the fuel pump is most likely malfunctioning; if so, this will require removal and replacement of the entire fuel pump, sometimes expensive, others not so much

You will need to replace the fuel level sensor which is in the fuel tank.They have a lot of problems because the metal fingers on the sensor wear off and gives you the incorrect readings.This will also cause the check engine light to come on.You will probably have a level sensor code.This will be a lot easier if the fuel level is down to about a quarter tank or less.Also you should be able to get just the level sensor and not have to get the complete fuel pump module.Good luck.

I have the same problem on my 2003 Dodge Ram 2500 5.7 Hemi. Also the gauge is sometimesslow to register after filling. Maybe 5 minutes.My neighbor has the same poblem with his 1999 Durango? I think this is a job for a recall.

the problem is with the fuel sending unit it is losing signal. the sender will need to be replaced this will require dropping fuel tank. or removing bed to gain access to top of tank.
