Anyway so far the take away message seems to be, do not run out of fuel or get too low, esp while riding hard & slow, and if you do maybe ride more conservatively to minimize heat build up.
Seems like a likely theory. I try to never let my tank get too empty for that reason, to keep the pump immersed.

I have read this entire thread, and my impression is that fuel pump failures generally aren't catastrophic, but rather, intermittent, and parking the bike for 20 minutes usually results in it starting and running fine (until the next occurrence). So I wouldn't hesitate to go out there on the WRR, and would replace it first sign of impending failure.
