My original question was I parked my truck in the drive and everything was fine. 2 hrs past and when leaving the break pedal goes to the floor. The question response I got this morning was master cylinder was bad. I replaced the master cylinder and bled the brakes, still no pedal any suggestions.
Do you
have the same problem?

Did you bench bleed master before install? Where rear wheel cylinders checked for leaks? And adjustment?

You can clamp off each brake hose and see if you still have a low brake pedal. They make hose clamps for just this purpose. You can also use vise grips with small tubes or bent pennies so as to not damage your hoses. If the pedal is high and hard you know the master cylinder is good and so is the ABS system.
