You can automatically run your "DismissMsg" function after a set timeout:
setTimeout(DismissMsg, 1000*60*15);

Just to clarify, your source would be changed to the following:
function SetCookie() {
        if (document.cookie.length > 0)
        {
                myCookie = document.cookie.indexOf("MsgCookie");
                if (myCookie != -1) {
                        document.getElementById('Msg').style.visibility = 'hidden';             
                }
        }
}
 
function DismissMsg()
{
    document.cookie = "MsgCookie";
        document.getElementById('Msg').style.visibility = 'hidden';     
 
}
 
// This will call "DismissMsg" once after 15 mins.
setTimeout(DismissMsg, 1000*60*15);

Just to do a little correction.. The code above will hide the box after minutes.. and in the question is showing.. so :
function ShowHideMsg(showing) // Old DismissMsg
{
   if (showing == "undefined") showing = true;
 
    document.cookie = "MsgCookie";
        document.getElementById('Msg').style.visibility = showing ? 'visible' : 'hidden';     
 
}
 
// This will call "ShowHideMsg" once after 15 mins.
setTimeout(ShowHideMsg, 1000*60*15);
 
//Code to hide : ShowHideMsg(false);
//Code to show : ShowHideMsg(true);

Please make the changes in the below code as soon as possible.

1. Show/Hide Div link will hide the link first.

2. After 15 minutes, div tag will become visible again without page refresh

Thanks

There is a syntax error in your above code, your missing a semi-colon after the onload event handler.

Also, you have some text "Open in New Window Select All" which appears below the closing html tag. You cannot have text below the closing html tag.

Just to clarify, "setTimeout" will execute a block of code once after the specified period. If you want code to run every 15 minutes, then you would need to use "setInterval" instead.
