The issue here sounds like it's the master cylinder failing. It is not retaining pressure when the engine is running. The reason they feel fine when the engine is not running is because the failing master cylinder is not getting power, and in essence is being bypassed.
If a pressure type brake fluid dispenser is available attach it to the top of the master cylinder. Other wise fill the master cylinder, start with the wheel cylinder that is furthermost from the master, and bleed until fluid comes out clean and free from bubbles. make sure to replenish the the master cylinder as needed. then proceed to the next farther wheel cylinder and repeat with the rest of the wheel cylinders. top off the master cylinder. Test with the engine off then with the engine running before driving.

Before installing the master cylinder you do need to bench bleed it. Some brake master cylinders come with a bleeding kit to make bench bleeding the master cylinder easier, purchase a bench bleeding kit if yours did not come with one. The master cylinder bench bleeding kit consists of adapter fittings that screw into the master cylinder and tubes that attach to the fittings of the master cylinder. Place the master cylinder in a vise and attach the brake master cylinder bleeding kit routing the tubes into the master cylinder reservoir. While keeping the tubes submerged in brake fluid of ther reservoir, push the master cylinder piston in repeatedly using a screwdriver. You will see air traveling through the tubes into the reservoir by keeping the tubes in the fluid you are preventing air from re-entering the master cylinder when the piston returns. When there is no more air traveling through the tubes the master cylinder is ready to be installed.
