Default Brake Pressure problem

I have this problem with my brakes that sometimes the pedal loses complete pressure and i have to let go and pump it once or twice to get pressure back. It started out with a spongy pedal and I have already flushed and bled my brake fluid 3 times. This last time the brakes were fine and then now the pedal loses pressure especially when traveling high speeds more often than not.

I am thinking maybe I need to change brake lines but before i go ahead and order maybe I can get some input on this.

If you're not leaking then it's not a brake line problem. Check for seized piston(s) just to eliminate the possibility of a bad caliper.

Sounds to me like the master cylinder is going out. I'm going to rebuild mine eventually just as a precaution so maybe you should too. Most of time when experiencing pressure loss, it's the master cylinder that should be looked at.
