Where does the grids loose their RecordSource? At design-time or at run-time?
If they loose their RecordSource at design-time is it possible that you close and reopen for some reason the tables that the grids are bound to. What kind of RecordSourceType do you use. Does this appear when you run only one form (this one) or you open and close other forms? Is the form modal?
