Query: Loved It only worked Once

I bought one to help clean up around my pond. The first time out it worked like a charm, however the 2nd time out the thing kept turning itself off. Since my husband "worked" on the switch I was unwilling to return it or get it repaired. I was all ready to order a relacement, however upon reading one review I am hesitant to have another go at it. The thing is the one I bought is sitting in the barn looking brand new but it won't even turn on.
