Method 1: Set trigger for the Popup using BooleanAnimationUsingKeyFrames.

 <Popup  HorizontalAlignment="Left" VerticalAlignment="Top" Width="200" Height="200" >  
                        <Popup.Triggers>  
                            <EventTrigger RoutedEvent="MouseMove">  
                                <BeginStoryboard>  
                                    <Storyboard>  
                                        <BooleanAnimationUsingKeyFrames Duration="0:0:3" Storyboard.TargetProperty="IsOpen">  
                                            <BooleanKeyFrameCollection>  
                                                <DiscreteBooleanKeyFrame Value="False" KeyTime="0:0:3"/>  
                                            </BooleanKeyFrameCollection>  
                                        </BooleanAnimationUsingKeyFrames>  
                                    </Storyboard>  
                                </BeginStoryboard>  
                            </EventTrigger>  
                        </Popup.Triggers>  
                        <TextBlock Background="LightBlue" > This is popup text</TextBlock>  
                    </Popup>  

Method 2: You can add Opened event for your Popup and set a Timer for it:
The code for the xaml:

 <Grid>  
        <Button HorizontalAlignment="Left" Click="DisplayPopup" Height="200"  Width="150" Margin="20,10,0,0">  
            <StackPanel>  
                <TextBlock>Display Your Popup Text</TextBlock>  
                <Popup Name="myPopup" StaysOpen="True" Opened="myPopup_Opened" >  
                    <TextBlock Name="myPopupText"  Background="LightBlue" Foreground="Blue">  
                          Popup Text  
                    </TextBlock>  
                </Popup>  
            </StackPanel>  
        </Button>  
    </Grid>  

The code to close it in cs:

private void DisplayPopup(object sender, RoutedEventArgs e)  
        {  
            this.myPopup.IsOpen = true;  
        }  
  
        private void myPopup_Opened(object sender, EventArgs e)  
        {  
            StartCloseTimer();  
        }  
  
        private void StartCloseTimer()  
        {  
            DispatcherTimer timer = new DispatcherTimer();  
            timer.Interval = TimeSpan.FromSeconds(3d);  
            timer.Tick += TimerTick;  
            timer.Start();  
        }  
  
        private void TimerTick(object sender, EventArgs e)  
        {  
            DispatcherTimer timer = (DispatcherTimer)sender;  
            timer.Stop();  
            timer.Tick -= TimerTick;  
            this.myPopup.IsOpen = false;  
        }

You can see for example : WPF: How to auto close a popup
