why in my 2013 ford fusion cutting out shortly after a fill up.

What is your question?

this happened twice. First time was about 2 weeks ago. I filled up the fuel tank and the next day the car cut off at a stop sign. It re-started ok but ran rough for about 2 minutes. I used a bottle of fuel injector cleaner and it ran ok. It happened today after another fill up at a different gas station. About 4 hours after the fill up, the car cut off at a stop sign again but it re-started again with no probled. should i start adding a bottle of fuel injector cleaner every ting I fill up from now on? Please help

What makes this problem better or worse?

It's better after using feul injector cleaner.
