This has happened to me. I had an account at one point that used to get 100+ likes on the majority of posts. After the introduction of the feed algorithm it went down to about 40-60 likes regularly, then at some point it dropped to <5 likes per post. I created a separate account on a computer that had never been used to login to an Instagram account before while at starbucks, and confirmed that none of the posts from my primary account were showing up under any of the hashtags I use regularly. I then followed my primary account from the temp account, as well as a few other random accounts, and the posts from my primary account never showed up in my feed. After a couple weeks of trying to resolve this with no luck I chose to stop using the account. I checked every couple weeks, and it took 4+ months for the posts to start appearing under hashtags and on users feeds again. I ultimately decided to just delete my account
