I filled my car up with gas and it started up right away. Went to pull out of the gas station and it stalled on me twice finally got it started and sped home. I checked the fuel filter and fuel pump and both are perfectly fine. I can get it started once a day and when I drive it it works perfectly fine but then ends up stalling out it seem's after the thermostat opens up. Im at a loss for what it could be. I changed the mas sensor and it's still stalling out?
Im at a loss for what it could be ??????? That's understandable when you have no clue as how thing's work on a modern automobile . checked the fuel filter and fuel pump ???? How ? Fuel pump pressure an flow test . Voltage drop test the electrical circuit .

Did you hook up a scan tool ? Not a code reader ! Check scan data ? What are the fuel trims at ? adding fuel taking fuel away ? Are the O2 sensors switching like thier suppose to ?
006 O2 Sensor Signal Analysis
010 Mass Air Flow Signal Analysis
Evap emissions system testing , stuck open purge solenoid . Over filled fuel tank . Do you top off the tank ? Or when fuel pump clicks off do you stop ? Loaded up the charcoal canister .
The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test.

Sounds like the results we had on a Jeep Cherokee after a friend showed us how well his heated pressure washer could clean up an engine comparment.
It took a couple of days before the Jeep ran normally again.
I think the splash caused some seepage into a connector, perhaps one connecting some sensor to the 'computer.'
Letting the car dry out if you can keep it running for 20 minutes or so until the engine is warmed up and then ignoring it for some hours might help.

sounds like an Ignition control module,check for spark immediately after it dies.the spark should should be strong even up to a half of an inch gap
