Why doesn't the simplest script in AHK work?

Question

autohotkey

Greetings, I wrote a simple script that clamps the spacebar for 6 seconds when you press F3. Please tell me why, when you press F3 (waited from 9 to 11 minutes of the hour), the space is not clamped?

~F3:: Suspend, Toggle
Loop
Sleep 1000  ; Keep it down for six second.
{
if(A_Min = 10)
{
Send {Space down}  ; Press down the key.
Sleep 6000  ; Keep it down for six second.
Send {Space up}  ; Release the key.
}
}

End::
ExitApp
