I am having an issue with losing brake pressure when trying to stop, brake pedal goes to floor. I have brake pressure before starting van and in park. Does not lose pressure until in gear.

First check to see if fluid is full in master, then if recent repair work was done on brakes have a mechanic use his scanner to open valves on ABS unit and bleed the system. Most likely it has air in it. I am assuming that there are no leaks in lines and brakes are in good working order.

No work has been done as of yet on the van. I noticed the problem last week, would lose pressure and pedal would go to floor. Pumped brakes a few times and pressure came back. That happen about three different times. When I went to leave my driveway yesterday had pressure in brakes until I put van in gear and went to stop, then brakes went to floor with no resistances. I am strongly leaning towards master cylinder.

Yes, it probably is the master has gone bad especially since you say it pumped up then went to floor.
