putting load on the ps pump may indeed stall the pump. here's what i would do: remove th belt and spin each piece: alternator, water pump, idler pulley (subtle, but these often are the real culprit). you won't really be able to 'spin the ps pump, but make sure you can rotate it all the way around by hand with approximately equal resistance.also, check your belt and see itf the grooved part of the belt is shiney. it should not be. a shiny, tight belt will still slip and squeal. if the belt shows any cracking or shiny-ness, then replace with 11720-1e400.
