sudden death of my pepper plant?

[fiffy]

I noticed one of my bell pepper plant started to wilt, all the leaves started to turn yellow. It was alright yesterday (or at least I didn't notice anything wrong with it). I didn't apply any fertilizer or done anything special in the past few days. Though it rains lightly these couple of days. But the other bell pepper plants next to it seems healthy. If virus/disease causes this, shouldn't all the other plants be infected as well? I'm really puzzled...

The plant having problem is the middle one.

If you didn't burn your plant with fertilizer I really have no clue does anyone else have any ideas.

Could also have been a "critter" that got it. Rabbits like peppers, so check the area for tracks and I'd sprinkle cayenne pepper all around the plants. Bunnies don't like hot.
