You must write it like this:

PHP код:

//global in the script:
new Float:DeathX[MAX_PLAYERS],Float:DeathY[MAX_PLAYERS],Float:DeathZ[MAX_PLAYERS],bool:death[MAX_PLAYERS];
public OnPlayerDeath(playerid, killerid, reason)
{
    death[playerid] = true;
    GetPlayerPos(playerid,DeathX[playerid],DeathY[playerid],DeathZ[playerid]);
    if(killerid != INVALID_PLAYER_ID)
    {
        SetPlayerScore(killerid, GetPlayerScore(killerid) + 1);
        SendClientMessage(killerid,COLOR_LIGHTBLUE,"Good Job +1 For killing that enemy");
        PlayerInfo[killerid][pKills]++;
    }
    PlayerInfo[playerid][pDeaths]++;
    PlayerPlaySound(playerid,4804,0.0, 0.0, 10.0);
    return 1;
}
public OnPlayerSpawn(playerid)
{
    if(death[playerid] == true)
    {
        SetPlayerPos(playerid,DeathX[playerid],DeathY[playerid],DeathZ[playerid]);
        ApplyAnimation(playerid, "PED", "KO_shot_front",4.1,1,1,1,1,1);
    }
    return 1;
} 


After OnPlayerDeath is OnPlayerSpawn called and you will be spawn after you are death. So you need an boolean (a variable) to set a value that you are death and spawn you back in OnPlayerSpawn.

My english is bad, but I hope you understand me.
