I've had similar problems with my Gas gauge as well. The first time the problem was occuring there was a resistor in the sensor which was shorting out and basically grounding the circuit which was causing the gauge to show empty and then maybe if I was lucky it would come back up. The second issue I was having was apparently caused (according to GM anyway) by a contaminant of some sort which was introduced into a gas pipeline which feeds the Toronto area. The contaminant was coating the sensor and causing messed up readings. So if I had 3/4 of a tank it might only be saying I had 1/2.
With the first problem I believe GM just replaced the resistor, the second time the tried some fuel additive to help remove the coating which didnt work, so they ended up replacing the gauge.

When GM acknolwedged the second issue they sent out Petro Canada gas cards for $20 of free gas along with the letter. The letter is also good for a free oil change.
