ok, I've made it and test it. Works fine.

at the top of script:

new money[MAX_PLAYERS];
------------------

OnPlayerConnect:

money[playerid] = 0;

-------------------------
OnPlayerDeath:

money[playerid] = GetPlayerMoney(playerid);

----------------------------
OnPlayerSpawn:

GivePlayerMoney(playerid,money[playerid]);

that will save your money summ after death and give it after spawn
