数秒間走った際に足の速度を変更する Unity3D

Question

Unity 3DでのゲームをStanderd Assetsを使って作成しております。

プレイヤーが数秒間走った際にライフを減らしていき、ゼロになった際に足の速さを0にするスクリプトを組もうとしているのですが、下記のスクリプトですと、プレイヤーを動かした際に5秒後に足の速さは0になるのですが、少しだけプレイヤーを動かした際にも5秒後にスピードが0になってしまいます。（time計測が走った際に開始されてしまうからだと思うのですが。。）

今後、ここにライフを3つ作成して3秒走るごとにライフが1つ減り、9秒後にはライフがゼロ。走れなくなった際に待つとライフが自然に2秒ごとに1回復。といったスクリプトを組みたいと考えているのですが、その前の上記の段階で止まってしまっております。

どなたかアドバイスいただけますと幸いです。

ThirdPersonCharacterではUpdateAnimatorメソッドを使用した際にismoveをtrueにするスクリプトを加えました。

走っているときにスタミナを減らしていくスクリプト

    bool runnnig; //走っているときにtrue
    float speed; //記録用のスピード
    float playerSpeed = 0; //実際にプレイヤーが動くスピード
    //speedとplayerSpeedは最初は同じ数値だが、speedはスタミナ回復し終わった時の代入に使う

    float count = 0; //数える用

    void Update()
    {
      if(running)
      {
        count += Time.deltatime;
        if(count >= 5)
        {
            //5秒走った
            count = 0;
            running = false;
            playerSpeed = 0;

            //5秒後にスピードを普通に戻す
            Invoke("SpeedModosu", 5);
        }
      }
      else
      {
        //走っていなければ0にする
        count = 0;
      }
    }

    void SpeedModosu()
    {
        playerSpeed = speed;
    }
