t sounds like you have a bad air switch located in your motor.
The air switch is what the air hose connects to on the back of the motor or on the box on top of the motor. The other end of the air hose is connected to the air button on the lip of the tub.
This is a latching air switch and when you push the air button it latches to send power to the motor. When the air button is pushed again it opens the latch in the air switch and stops power going to the motor shutting it off.

Perhaps the shut off valve is not fully open, or constricted. Try opening and closing the shut off valve to loosen any sediment. Otherwise, replace shut off valve.

It could be a venting issue. Check the roof vent for the plumbing system. Perhaps clogged with leaves or other debris causing a blockage in the vent line. You can use a hose up to the roof and flush out the vent line. Another problem may be calcium buildup. CLR , a product available at most hardware and grocery stores will dissolve mineral buildups.

If you've tried turning off both shutoffs underneath and water still runs, then the shutoffs are also likely worn out and need to be replaced. If there is no way to shut off from that point, then the only other option is to have somebody turn off all water in the house near your water meter or main water line. In many places, hardware stores will sell something called a "water shutoff key", but depending on your location, it may have a different local name.
Once water is off to the whole house, turn the hot water on somewhere in the house to reduce pressure from your water heater before replacing your faucet and shutoff valves.
It is a good idea to take one of your old water shutoffs with you to a hardware store to make sure the new one would fit propperly.
If you know somebody who can take apart the faucets to check and replace just the washers, then it could be fixed with even less expense, if you would not rather replace the faucet with a new one that will last longer.

This sounds like the air switch in the motor is not working properly. You will need to remove the pump from under the tub to access the air switch located in a housing on the motor.
Replacement Air Switch will cost you about $20

Two things come to mind,
The sinks were installed out of balance and way over tightened causing a constant stress on a warped surface, or a foreign object was left under lips of sinks. If they were purchased and installed at the same time you could have received damaged merchandise.

You may have to use a really neat tool and that is aunt splitter. You can get it at O Reilly's auto store or any of those stores. That should remove it.

There is a clog in the line. A plunger usually solves this problem, but you have to use a toilet plunger. Your local hardware store will give you the right tool ($13). If the plunger doesn't work, you need a toilet auger (also called a closet auger), which you can buy for less than $20.

Shut the water off flush toilet and there should be two bolts that you can see at the under side of that tank. You need to remove them bolts and lift off the tank and install a new seal. Sometimes i mean sometimes you can tighten them a little and they will stop leaking. If it has been for awhile id just replace it.

Check the aerators for debris. Aerators are located at the end of the spout where the water comes out. Usually these unscrew counterclockwise (some models require a tool). Rinse out and reinstall. They may be just a lower flow model.
