My 95 Bonneville will run without stalling until the fuel gauge gets to about 1/2 empty. Then I can only drive it a short distance before it stalls. If I touch the accelerator very gently it wont stall (unless I put on the brake or make a hard right turn). This use to happen only when it was almost empty. Now it happens when it is about 1/2 empty. Between 1/2 and full, the fuel gauge will sometimes swing wildly. After several times of this happening the same way, I just fill it up at 1/2 tank and it quits stalling. When I fill it at 1/2 tank, it will take about 10 gallons and my tank only holds about 16 gallons. I am contemplating replacing the sending unit and slosh unit. This began after I filled up with some dirty gas in Louisiana. Then, even with a full tank it would stall on the highway after driving about five minutes. Now it has happened a second time after filling up in Louisiana (at a different station). I wonder if there is a lot of dirty gas there. And I wonder if there is a lot of dirt still in my tank that clogs the sending unit when the tank gets low.
