Aside from the 3hp intelliflow, I have not found a pump which is clever enough not to commit suicide when the water stops coming.
I'll skip the rant about the short-sightedness of relying on the water being pumped for cooling - there are air-cooled motors available.
If there are no pumps with such a switch, does anyone make a controller which monitors water flow and breaks the circuit when pressure drops?
(yes, I do have yet another pump dying on me. I killed the first one; I took a chance with a used unit and crapped out.)

And, just to make things interesting:
Is there anything "special" about pool pumps? If I could find a sump (or garbage) pump rated for continuous duty (with a float switch - what a concept!), is there any reason I couldn't drop in in the skimmer sump and plumb it into the filter? A bit of stainless/brass screening over the skimmer inlet could replace the basket's function (or plumb a dead pump in the line just for the basket)?
I have a pump I use to drain the thing - it's too big to fit the sump, but a 2" pvc line coming out of the deep end might not be all that obnoxious - and replacing a sump pump is much cheaper than a pool pump.
