Most likely a vacuum leak effecting the O2 Sensors

That is your 4 codes.

Have the Evap System checked also, for leaks

Fuel Filter--filters fuel,doesn't fix anything

I had a similar problem. Turned out it was a bad fuel rail pressure sensor. Thew a OBD-II Code P0193. Bought a new sensor and installed it in about an hour. Easy. $40. Depressurize the fuel system first by disconnecting the switch under the jack cover in the rear of the van.

The latch has come apart is some aspect. Remove the inner panel and manually open the latch. In most cases its just a plastic clip that has broken.

You can get the EGR Valve for $80.00 OEM Motorcraft
Part, on the internet and install your self

The code better be for an EGR Valve issue or
be having issues going up hill under a load or

What Type of Warning it is ?

Sounds like it's time for the factory mileage service, wise to have your dealer check it over, that many miles could run you into some problems soon, be proactive and have it looked at.

This definitely sounds like you could have a loose alternator belt or the alternator itself is going out. While you are pressing on the brakes, you have to draw power from the to light up the brake lights, if the alternator is not functioning properly, you are draining the battery and this will cause the car to shut down

It can be the pads. The wheel sensors count the revolutions of each wheel. On some rear drive differentials there is a sensor in the Differential that can go bad. But if the Brake pads are in pieces, the wheel sensors view can be blocked and the sensors lose count.

The Traction control will activate. Traction control can work in several ways. Some controls activate the rear brakes until both rear wheels are spinning the same RPM. This is destructive to the brake pads. Additional Traction control will cut the engine by choking it or interfering with the Ignition. When the rear wheels spin the same RPM, power is restored. This system is easier on the brakes.

The Emergency brakes are inside the rear Rotor if you have 4 wheel disc brakes. The sensors are in the Drum portion of the Rotors. A lot of Brake shops fail to check the E brakes because so much has to be disassembled. Your Mercury should have a Button on the dash to turn off the feature. Turn it off until you can have it checked.

Remove the fuel pump relay then try to start vehicle, this will relieve presure in line. Some fuel will still leak out when you remoe filter. Have a pan to catch the gas, also the filter will be ful of gas.

Hope this helps you.
