Lost power steering about 80K miles. The belt is new and tight, replaced pump and added new fluid. Power steeing worked fine for a few hundred miles and then lost power steering again. Thought it might be the rack but didn't have enough money to replace. Drove about 1000 miles without PS and all of a sudden it began working fine again. Are there any electronic systems that could be creating this problem?

sound like you have lost presure switch that is supposed to relive presure when presure is high or the belt is too tight putting presure on the bearing causing over heat or oil cooler restricted and not coolling the oil
Check the power steering fluid, it could be that it's just low. If it's full it might be time to get it changed. Also check the tension on the motor belt. If it's loose you won't get full power to the pump.
If the belt and fluid levels are correct there is a good chance it may be a bigger problem. The power steering pump may be the fault. At lower speeds a worn pump isn't turning fast enough to push enough fluid. When you REV the engine your speeding up the pump pushing more fluid. Get the pump checked. If that's ok your possibly looking at a problem with the rack itself. ($$$ Ouch!).
It sounds very much like your power steering pump is going out. It was very good to check the fluid, something else that you may want to check is the tension on the belt that is turning the power steering pump. In few cases a worn belt can lose it's grip on the pully, especially if it's cold outside. Also, sometimes the tension pully is bad and isn't able to keep the belt tight enough to get a good grip on the pully.
If you are sure the whining is comming from the power steering pump, you will most likely have to replace it.
CHANGING POWER STEERING PUMP YOU HAVE TO PLACE A DRAIN PAN UNDER THE VECHICLE. SIPHON OUT POWER STEERING FLUID WITH A SIPHONER DONT USE YOUR MOUTH TO SIPHON SWALLOWING POWER STEERING FLUID CAN BE FATAL MAKE YOU SICK.WHEN ALL POWER STEERING FLUID IS REMOVED FROM POWER STEERING PUMP.REMOVE DRIVE BELT.THEN REMOVE THE POWER STEERING PUMP.THEN YOU HAVE TO REMOVE THE POWER STEERING PUMP PULLEY THE NEW POWER STEERING PUMP DONT HAVE A PULLEY YOU HAVE TO HAVE REMOVE PULLEY FROM THE OLD POWER STEERING PUMP.YOU NEED A PUMP PULLEY REMOVER AND A PULLEY INSTALLER.YOU CAN TAKE OLD POWER STEERING PUMP AND NEW POWER STEERING PUMP TO A MACHINE SHOP.THEY WILL REMOVE PULLEY OFF OLD PUMP PRESS IT ON NEW POWER STEERING PUMP.THAT WOULD BE CHEAPER THAN BUYING THE PULLER AND INSTALLER.GO TO AUTO PARTS STORE BUY NEW HIGH PRESSURE LINE O RING GOES TO PRESSURE LINE GOING INTO POWER STEERING PUMP.ONCE YOU GET NEW PUMP READY PULLEY BEEN PRESSED ON.TAKE POWER STEERING PUMP HOME PUT IT ON.
