Here. I made this stock:

menu_set_timeout(const id, const iMenu, const Float:fTime)
{
    static iArray[2], iTask
    static const TASK_MENU_TIMEOUT = 456522
    
    iArray[0] = id
    iArray[1] = iMenu
    iTask = id + TASK_MENU_TIMEOUT
    
    remove_task(iTask)
    set_task(fTime, "RemoveMenu", iTask, iArray, sizeof(iArray))
}

public RemoveMenu(iArray[2])
{
    static id, iMenu, iNewMenu, iOldMenu
    
    id = iArray[0]
    iMenu = iArray[1]
    
    if(player_menu_info(id, iOldMenu, iNewMenu))
    {
        if(iNewMenu == iMenu)
            show_menu(id, 0, "^n", 1)
    }
}

Use

PHP Code:

menu_set_timeout(id, menu, 15.0) 


after creating the menu. 15.0 is the X seconds, menu is the menu id (g_Menu).
