Possibly too much rain, they may have a root fungus.

Because the fungi in the soil are not everywhere the same and plants have
different resistence to them.  I have had two eggplants drop dead from
fusarium wilt leaving the others OK.

 There are insects that bore out the center of the stems, usually the plant just
snaps at a weak point, but sometimes they wilt.
