First replaced the thermostat then check on condenser unit that's outside .make sure the fan is running when compressor runs .if not there is your issue .If fan runs and compressor keep shutting off you might have a dirty coil so clean it out with water or you might have a leak in the system causing unit to shut off on low pressure .if this is the case you need to call a service technician .
Try simple things first like clean coil ,capicator and fan operation.
SOURCE: Compressor starts and doesn't stop
Relay for the compressor may be stuck ( Contacts welded) both the fan and the compressor should operate at the same time. Have the relay(s) checked and possibly replaced.
need more info. Is the fan actually on full force or does it feel like the air flow is restricted (could be dirty coil or filter)
Is the fan on full force but only warm air coming out (compressor not working)
Is the fan on but only cool not cold air coming out (freon leak)
The more info you give the easiest it is to troubleshoot from here.
hope this help

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of
tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.
