I had very similar symptoms after a long day's riding and lots of miles during recent tour. It was ok once you got up in to higher gears but in first and second in particular and third to lesser extent even quite gentle acceleration load caused some really horrid clunks, both heard and felt. Interestingly came on quite suddenly, didn't develop slowly throughout day.
Good lube of the chain sorted it, was worried that the dry lube the group had bought wouldn't do the job but was nice and smooth again next morning.
What you using no the chain? How much slay does it have side to side and when pulled away from rear sprocket?
Suggest a good degrease and soak in lube first thing to try, I use engine oil makes mess and washes off in rain but penetrates well.
