If it is a small leak then it might simply be "blown away" by airflow from either/both of forward movement or fans. Once stopped the fluid "collects" and becomes visible, especially as, already said, the pressure in the system is higher a short time after switching off than it is when running.
One method of finding small leaks that can work is coloured food dye - bright yellow - added to the water.. makes it far easier to see, and dries to leave a stain that can be traced, another is to use blue "kimwipe" type paper cloth, this gets much darker when wet than when dry, and it stays like that for a little while...... so wrap it around suspect areas, secure with tape, go for a drive and then look for the colour change, might help you pinpoint the leak ??
I've used both methods with success in the past.
