Naruto never lost their chakra. Naruto just ran out of their chakra temporarily, and it regenerated. The proof behind this is that only those with the chakra of all the tailed beasts and Rinnegan can undo Infinite Tsukuyomi. Naruto and Sasuke did the special hand seal, and together they undid it, and this was shown before Sasuke released Kurama and the other beasts from their chibaku tensei prisons. Therefore, they never gave Naruto anymore chakra or anything like that. Naruto did it with the chakra he already was given. Hagoromo specifically wanted Kurama to go back inside of Naruto because Naruto is the Jinchuriki of all of the Tailed Beasts and their meeting ground since he has all of their chakra and united all of them for the first time in centuries. He was the Child of Prophecy and the boy Hagoromo talked about that would unite all of the beast in the future. Obviously the power he was given was permanent, do you guys think Hagoromo expected Naruto to never use the tailed beasts' chakra ever again? It's clearly permanent.

As for The Last, Naruto had manifested Kurama outside of his body, so that would be a logical reason for why he didn't use SPSM because Kurama was already using most of his power. That, and if Naruto used SPSM, the final fight would be over in an instant since he would one-shot Toneri. In Gaiden, he used SPSM but only with Kurama this time. That doesn't mean he doesn't have the other tailed beasts, maybe he just found no need to use them at the time and go all out against a single Shin clone? Ever thought of that? Anyway, how about we all wait until we see the Boruto movie and then see whether he still has them all or not. Alright?
