Sounds like you have a Algae problem in your fuel. Apparently there are somewhere around 100 known bugs, bacteria, fungi and who knows what else that can and do live on diesel fuel or components of diesel fuel. Getting rid of the sulphur in diesel fuel has worsened the problem. Apparently also you can get an infection, for the want of a better word, in your fuel from just one contaminated fuel hose pour. Check this out as there are tests for algae contamination in fuels.
