pawn Код:

forward Transferring(playerid);
stock Transfere(playerid)
{
    SetTimerEx("Transferring", 3000, false, "i", playerid);
    TogglePlayerControllable(playerid, 0);
    return 1;
}

public Transferring(playerid)
{
    TogglePlayerControllable(playerid, 1);
    return 1;
}

this would be one way to do it..
just write "Transfere(playerid);" where you want the player to be freezed.
