Also, what temperature is it fermenting at, and how much yeast did you pitch? It could be just be moving very slow in which case bottling would be a bad idea.
7lbs of 2-row
1lb of crystal 15L
1lb of crystal 40L
5lbs of ultra light extract
2 packets of S-05 (rehydrated)
Pitched yeast at about 72F temp increased to about 75F during the violent fermentation. Had a few very cold days and the temp dropped to 63-65F range, which is where I think this may have gone awry. it never seemed to recover even after swirling and raising the temp to 72F.

I've never heard of adding Beano to a stuck fermentation. I have seen people talk about adding yeast nutrient and yeast energizer when re-pitching, but I've never had such a large discrepancy in the FG. I have had issues with not getting as low as expected while using extract, but usually only 1.024 when expecting 1.018.

That's a ton of crystal malt in a 5 gallon recipe, plus the extract probably has lots, particularly if you are finishing at 1.024. Your beer might be done at 1.033, but pitching more yeast at high krausen wouldn't hurt it. Be careful about oxidation, though.

I wanted more of an amber IIPA. I may just try some yeast nutrient/energizer first and see if that will re-start the yeast.

I don't think the energizer/nutrient addition alone will wake em up.
I'd make an S-05 starter, and add that to the secondary at high krausen, like pdxal said.

That's a little more crystal than you might find in other recipes, but wouldn't expect that to be all of the problem. What was the mash temp? Have you checked your thermometer in boiling water?

This may be of interest:

Mashed at 152F and Sparged at 168F. It wasn't the crystal malts, I am thinking that the LME didn't have a great amount of fermentable sugar in it (part of the reasons I've had trouble reaching expected FG on my earlier brews is my guess).

You are correct, the energizer did not roust the little beasties. I had rinsed the yeast from another APA and made a starter and pitched that 24 hours after making the starter. Within an hour the airlock on the IIPA was bubbling, which I'm hoping is a good sign that I'm back under way.

That didn't change anything. I ended up dumping the batch. It tasted of unfermented extract and I was spending more trying to get it restarted than I spent on it to begin with.
