1. Coolant level: If the coolant level is low, the engine may overheat and cause the car to cut off. Check the coolant level in the coolant reservoir and add more if necessary.
2. Faulty thermostat: A faulty thermostat can prevent the engine from cooling properly, which can lead to overheating and the car cutting off. Test the thermostat to see if it is working properly.
3. Water pump: A faulty water pump can also prevent the engine from cooling properly. Check the water pump to see if it is working properly.
4. Head gasket: A blown head gasket can also lead to overheating and the car cutting off. Check the head gasket for leaks.
5. Fuel pump: A faulty fuel pump can prevent the engine from getting the fuel it needs, which can cause the car to cut off. Check the fuel pump to see if it is working properly.
6. Electrical issue: An electrical issue, such as a short circuit, can also cause the car to cut off. Check the electrical system for any problems.
If you are unable to identify the problem yourself, it is best to take your car to a qualified mechanic for diagnosis and repair.
