Detailed Answer:
I read your question carefully and I understand your concern.

I assume that those episodes you describe make you worry about a neurological cause being at the root. It seems your episodes have a potentially peripheral component in terms of the symptoms appearing when you use your tongue muscles and a potentially central brain component in terms of not finding words.
I would say brain lesions like a tumor, infection or peripheral nerve disorders are not likely due to the transitory nature of your symptoms. Nor do those episodes resemble typical transient ischemic attack manifestations or partial seizures.

There are a couple of neurological conditions parts of that description might evoke. One possibility given the appearance of the symptoms when you have been using the speech muscles for some time could be myasthenia gravis, a condition which manifests by weakness of the muscles, which increases as those muscles exercise, would explain the heaviness. Commonly it involves small muscles like those responsible for eye movements and articulation. However doesn't really explain the word finding difficulty.
The other possibility which might explain the word finding difficulty might be a disorder like dementia involving cognitive functions such as speech. That on the other hand doesn't explain the tongue heaviness sensation.

What I would consider a more probable cause though for those symptoms in my opinion would be them being a manifestation of anxiety which could fully justify those symptoms and is a very common and widespread issue.

So if you want to get reassured you could have a neurological exam to test for muscle weakness and test cognitive functions which would be involved in the disorders I mentioned, but I believe anxiety to be a more likely cause.
