Spark in kitchen GFI electric outlet?

A few times I noticed a spark inside my kitchen outlet when I went to go plug/unplug something. It is a GFI outlet, so if I had any problems I would just hit reset and go on my way. Then today anytime I tried to use the outlet it was a few minute process of me hitting the reset button before it would work. Now I can't get that outlet or the one 5 feet away (regular outlet) to work. I don't keep things plugged into outlet unless I am using it (toaster, blender, or panini maker are the only things I have used in that outlet, only one at at time). The regular outlet has a phone and Krug coffer machine. I have tried switching the switch in the fuse box, but now I can't get either outlet to work. Any advice?
