Stuck fermentation

[udiraz]

Hi All.

I started to make a mash from dried apricots. you can see the thread about it here: viewtopic.php?f=38&t=74249.

Well, for the first few days it was bubbling very nice, and than, two-three days ago it got stuck. First it went very slow, and now it is completely stuck.
I tried to put some more yeast (1118) but it did not help.
It stopped at about 1.035 SG, so there is more sugar in it.
We did have an extreme heat wave in Israel ( we had about 40 degrees Celsius), but I did put the yeast also after it went down to normal temperatures. I also have to mention that I fermented successfully grapes in the Israeli summer, so I am not sure that it is the heat that stopped it.

I also tried in one barrel to filter the solid parts, and add more filtered water (to eliminate the possibility of too high alcohol concentration) and add more yeast after dehydrating of course. didn't help.

Any good advice ?
I am really desperate here...
