depending on how your system is plumbed pressure switches are available with low pressure cutouts that will shut off on low pressure.
Square D FSG2J21M4CP 30/50 PSI Standard Pressure Switch with Low Pressure Cutoff
Tempting. That's almost a perfect, low cost solution. Only problem is, there could be a leak condition where the pump is still supplying enough pressure to not trip the low-cut off. Would have worked in a situation like my original post (completely sheered line), but a crack in the PVC, even spraying water under pressure, might not drop the pressure enough to cut off the pump. It also has to be reset after power failures, which happen a bit too frequently where we are.
