Q: bought a 2014 civic and filled the tank yesterday for the first time. the gauge says 3/4 full and it stalled 3 times.

Just recently bought this car 10 days ago. No issues except the tire pressure light won't go off. The real issue is yesterday I filled the tank to full for the first time and when I turned on the car the gauge only read 3/ 4 full. So I thought that was weird. I then pulled out of the gas station onto the main road, got to the first red light, stopped within 5 or 10 seconds. It vibrated a little then stalled. I then put it in park started the car and kept going. I then pulled up to the next light and it vibrated and almost stalled. Got to my destination then proceeded on my way home. And as I was turning in my alley it kind of died and I coasted it to my driveway since I was right there. Can't remember what dash lights turned on. But I drove it to autozone today to have a diagnostic and altenator/starter/battery Checked and it was all fine. The autozone woman said it could be bad gasoline. And we have had quite a bit of rain the last week. 7 inches to be exact. Not sure what's going on

My car has 35000 miles.
My car has an automatic transmission.
