When the car ingine off what is the problem

Thank you for contacting us 
Dear sir 
First try to jump start with other car.
- if it started then you have to check your car's alternator and it's belt.
- if it's start and turn off immediately then don't try starting it and the possible faults is :
1. Timing belt or chain.
2. Crank sensor. 
3. Fuel pump and the filter.
4. The immobiliser. 
So you have to check your car by the OBD ll device at a specialist
