Default problem with all grain not fermenting.

I brewed a peanut butter chocolate milk stout all grain about 2 and half weeks ago. I used pb2 for the peanut butter, one lb of lactose and grain and hops. The og was at 1.061. I pitched a smack pack of ale yeast and nothing happened. After four days I pitched some dry yeast saleale 04 and nothing happened. I took a reading yesterday and the sg was at 1.061. I rehydrated another safeale 04 yeast in warm water waited 25 min and pitched. As of now nothing is happening. I will check the sg tomorrow. I dont know what to do. I can see one or two yeast being bad but three? There are no odd odors coming from the wort. It smells like malt and yeast. The only issue during the brew was in the mash tun. The temperature of the mash tun was 150 when I sealed it. I use an igloo cooler. I think the problem could be the long starch chains didnt convert into simplier sugars for the yeast. But I dont know. Is there anyway I can save my batch? Is there anything I can do besides dumping it? I have more yeast but I am reluctant to pitch more into it? Any help would be appreciated.

Something would ferment. What you are describing is impossible, unless it is sitting at 34F.

You didn't say, so I'm going to ask the obvious...

Are you using a hydrometer or a refractometer? Is it possible that it isn't calibrated correctly? What temperature did you take your first gravity reading at? Did you correct for that temperature and your hydrometer/refractometer?

I dont waste peoples time, I am not here making something up to pass the time or for fun. I have a problem with my latest batch and am looking for solutions or anything to why this would be occuring. Ruling out bad yeast (so far I have pitched three times) I dont know what to do. I have more yeast i can pitch and will do so if my next sg reading is the same as before. I am simply asking for help, I have been brewing for 5 years and never ran into this problem. This problem is 100% frustrating and disappointing. If you can give me help I will be grateful. If you believe I am on here wasting your time or others than dont respond to my thread. I am simply looking for help. If you believe my problem is impossible for it to occur than so be it you cant help me. I thought and still do think that this forum is for helping others with questions, problems, or anything home brewing related. And that is why I asked. I have researched online and in my brewing books and have not found any case of this happening. That is why I asked here. Again if you can help me please do.

Does the wort taste sweet? Have you tried an iodine test?

Is there any chance you introduced potassium sorbate into your brew?

That's what I was wondering. If there was some in the peanut butter perhaps?
