What could be the problem-did my gas cause this?

The "check engine soon", "ABS" and a wrench symbol lights have all lit up on my dash board. It started after I put gas in my truck. About 10 minutes later I was on my way to KFC and my brake petal started to pump when I slowed down and one by one all of these lights have come on my Mercury Mountaineer 2004. I havent had problems out of her all of this time and she has been running fine until now. She will drive, just slower and its harder to turn my steering wheel. Could it be the gasoline I put in my car that could cause this? Ive checked the owners manual and some of the signs point to this and some don't. Any help would be great. Thank you.
