fire and smoke in cycles

I’m trying to get some nice cycles fires and smoke
and I set render at 200 frames and also the smoke at 200 frames
then baked it

but when I render this it goes well up to 100 frames and after that the fire get smaller and smaller very fast
and nothing is left at the end of 200 frames

how can this be corrected ?

thanks for any feedback
