Tarik,
a fast search for bootstrap and "time series" at
http://finzi.psych.upenn.edu/search.html
show some interesting packges that already exists: waveslim and boot.
The first uses wavelet techniques to decompose the series and then
bootstrap it using the function dwpt.boot. The second resample time
series in blocks or based on models. This seems more appropriate to
your needs.
Take a look at these packages and others using the site above.
HTH,
Rogerio.
