I recently did work to my brakes, I have checked and double checked to see if anything is leaking. It's not. I bled the system and have pressure on the brake pedal when the vehicle is off but when it is running I need to pump it a few times. Any ideas, I think my Master cylinder is bad.

Do you replace calipers? If so make sure they are on the right side also make sure they are bled

No I didn't replace calipers I patched lines. No leaks now though.

I would bled till you have new fluid if that doesn't work replace the master

I bled for a while and I even put a vacuum fun on and didn't get much out of it.

I would replace master cylinder. Probably an internal seal leak.

Also make sure the rear brakes are adjusted correctly that can cause this problem too

Ended up it was the master and there was also a little air in the calipers
