That sounds similarly to my condition, but I'm just in my early thirties.

I was stuttering since I was a small kid. In high school, went to therapy and I was stutter-free for around 8 years, then I started to stutter again. Since then, I have a better and worse periods, I can speak without much stuttering for as long a quarter of a year, then suddenly start to stutter even doing small talk with the family.

Regarding losing words, I really like your analogy with blank dictionary entry. It's like, "I can speak without stuttering as long as a... what is the word for a period of three months?", then I need to search my memory for this word, and quite often I can find the word I'm looking for, but it takes time. I had these symptoms as a child too, but they have gotten a bit worse in recent years.

I always half-jokingly thought there must be some consequences of being born almost 4 months ahead of schedule.
