pawn Code:

OnPlayerDeath(playerid, bla bla bla){
if(FindTime[playerid] !=0)
{
        ShowPlayerMarkers(0);
    FindTime[playerid] = 0;
}
//...

I think this should work. After he dies it will remove all markers.

And in the timer which sets remaining time post this code:

pawn Code:

new bool:flag=false;
for(new i=0;i<MAX_PLAYERS;i++)
{
    if(!IsPlayerConnected(i))continue;
    if(FindTime[i] !=0){
    flag=true;
    break;
    }
   if(flag==false)ShowPlayerMarkers(0);
}

This should remove markers after time expires.
