This happens when the brake booster push rod is adjusted out too far which does no allow the brake master to return fully holding the brakes on . To confirm the issue loosen the brake master mounting bolts 3 turns to see if the car starts to roll again, if so remove the master and adjust the booster push rod inward. When it acts up see if it will coast downhill on its own in neutral, or if you can push it by hand. If not, open the bleeder screws on the front calipers to see if one will release. If it does not, suspect a sticking caliper. If it does release, try it again by cracking open the steel lines at the master cylinder. If they release there, suspect contaminated brake fluid.
