This is a very tiny puppy (similar to what my Marcel was at that age) - he should be eating every 3-4 hours at this point, if necessary for him (and it's very likely that he may need it that often).
FIRST, she needs to visit the vet and have him thoroughly looked over; they will likely want to do blood work.
Secondly, it is unclear to me whether or not giving Nutrical is bringing him out of these episodes (it kind of seemed to bring him out the 2nd episode, but not so much the first). IF the Nutrical IS bringing him out of these episodes, then yes, it's probably from hypoglycemia. What's really scary though is that, given the severity of his symptoms - this hypo. is getting to the extent where I fear he could actually die from it - in other words, it is being noticed/caught WAY TOO LATE.
There are times when people should use Nutrical on a more regular basis (given a clean bill of health otherwise, that is) - and this is one of them, in my opinion. Your friend should give Nutrical right before going to bed at night, immed. upon waking, and even possibly mid-day if necessary. Nutrical is not just *sugar*, despite what some folks say - read the ingredients and you'll find otherwise. Your friend needs to feed this baby often to keep the blood sugar more stable. If she doesn't do these things, I fear she could lose this baby. It is very possible that he had a seizure from his last episode - at which point he foamed at the mouth and lost some urine (which is what you're describing) and arched his neck.
