Would like to know why my convertible well jet pump is over heating and shutting off

Only guessing but think it is a rough bearing in the motor. Pump should run relatively quiet but there is a possibility that the plastic impeller is binding if it ever ran dry as it could have overheated and melted.

How to fix a wayne pump ycb 139-3/4-2b2 from over heating?

Dirt will cause overheating.
Lack of lubrication. Bad bearings. Temperature where the motor sits They are not to sit in high temperatures.
Sometimes the electrical wiring is not heavy enough to carry the electrical load and causes over heating. Worn electrical components in the motor will cause over heating. Sometimes if a motor is over worked will do it as well.

Foltec 4012-10 motor get hots and kicks off

Sounds like a seized bearing. Many times the motor boosts its torque output to get over the initial inertia. and if the bearing seized, the motor running at normal capacity would not be strong enough to rotate. thus causing the rotor to stall and hence the motor getting overheated.

Hayward Swimpro Sand filter shuts off after approx 2 minutes

It sounds like the pump is either overheating or the thermal protection switch that senses the overheating situation is defective. If nothing else changed like running on an extension cord, etc, a small motor repair shop can get you back up and running fairly inexpensively.

The motor keeps turning on & off like it is overheating

it sounds as if it is overheating. there is a sensor inside all motors that shuts the motor down if it reaches a certain temperature.
If your motor shuts down after running for a while then 15 minutes or so just comes back on then that is what is happening.
Could be the result of not enough air around the motor to keep it cool, or something inside the motor making it work harder than it should like the bearings going out.

Jet Pump stops after three starts of 20 minutes each and it doesnt want to start back again until the next day or after a few hours

check motor with hand after it stops for excessive heat. Thermo coupler shuts motor off if overheating, to protect windings. Bad motor bearing can cause overheating, if so should hear bearing noise when running.
Also check start capacitor, by removing and checking with ohm meter, or plug in oposite terminals of capacitor to charge. Place rubber glove on hand, and contact two oposite terminals with screwdriver should produce a small spark.
