Car keeps stalln out and i got good fuel pump and relay

My car has 120000 miles.
My car has an automatic transmission.

Any number of components can cause a stalling issue. It can be as simple as a vacuum leak, to as severe as an engine control unit or more. If there is a vacuum leak caused by a broken intake hose, vacuum line, or intake manifold gasket for examples, the air/fuel mixture will be too lean from the additional air, and the engine could be low on power and even stall. Also, any of the numerous sensors or switches that the ecu read information from the engine, coolant temperature, crankshaft position, mass air flow,etc. can all lead to stalling issues if any of them are bad, shorted, or not reading properly. Have a certified technician inspect the vehicle to find the exact cause of the stalling.
