Car stalling at idle after topping it off.

When it does this get out and take the fuel cap off. If its the vent tube you should hear a suction release from the fill tube. You may have two problems a partially clogged vent and a weak china fuel pump.

I remember years ago I had this problem and I put a new Direct Connection pump on the engine. I partially collapsed the tank with excessive suction from the new pump. There was a mud dauber wasp in the vent line .

Blow out the vent tube and get a upgraded pump.
