There's a lot of error in your code for example you created a variable called Death and a callback called Death that will give you an error error 021: symbol already defined: "Death" and error 010: invalid function or declaration

This code should work.

//macro
#define function:%0(%1) \
    forward%0(%1); public%0(%1)

#define DEATH_TIME \
    25

//variable
new 
    SecsToGo[ MAX_PLAYERS ] , DeathTimer[ MAX_PLAYERS char ];

public OnPlayerDeath( playerid, killerid, reason )
{
    SecsToGo[ playerid ] = DEATH_TIME;
    DeathTimer{ playerid } = SetTimerEx( "Death", 1000, true, "i", playerid ); //timer
    return true;
}

function: Death( playerid )
{
    if(0 < SecsToGo[playerid]) //Yoda Conditions
        SecsToGo[playerid]--; // decrease the timer per second if it's more than 0 .

    if(0 > SecsToGo[playerid]) //Yoda Conditions
        KillTimer( DeathTimer{playerid} ), SpawnPlayer(playerid); //stops the timer and spawns the player
}
