If your able to see what the fish are doing, short strikes etc. try using a jigging movement as opposed to a strip and pause retreive. I have experienced what you are seeing many times while float fishing in my kayak and have had success using this method. Most times I can watch the bass inhale the fly right near the boat. Be sure to set the hook using a down current sweep instead of the usual rod lift. My go to fly is the Clouser foxy redd minnow. Hope this helps.
