Beginner Gardening: Pole bean help please!, 0 by bunsengirl

I built a raised planter and a trellis for my first-time green beans (Kentucky Wonder). Immediately they shot up and most are climbing 4 feet up after only 3 weeks. Suddenly one plant at a time is failing. No obvious bug infestation. One plant just suddenly wilts up like it really needs water but doesn't recover. The first time it happened I pulled the plant out of the ground but couldn't find any bugs in the soil and the root system looked intact. Now a second one has fallen prey but I've left it in the ground so whatever's eating it will continue to do so instead of moving onto another while I'm trying to figure out what to do. Any suggestions?

(The sturdy wooden frame is covered by chicken wire and extends over the top of the fence so they should have plenty of room to grow. Good soil amendment, good sunlight. Got to be some kind of root bug.)
