This is due to the way GNU Radio decides when a flowgraph is done. Since the audio rate is so low, most of the wavfile fits in the block buffer, the block sees that there is no more data to load and declares itself done.
There are buffer size controls that might help. On the advanced tab for the wavfile source, try setting the MAX output buffer to something like 256 and see if that helps.
