Hello, I've been mining various altcoins via cpuminer on a couple of pools recently.

Do I understand it correctly that the work done between two 'Stratum detected new block' is lost in case there were no 'yay's in between?

Every time you see a 'yay' it means you submitted a valid share.

When you submit shares, you receive rewards from the pool.

If you don't submit any shares, you don't get paid.  

Yes, it is true, but it doesn't answer my question.

Let me answer my question myself then.

No it doesn't. The only situation when the work is lost happens when it says 'booo' in the logs.
Which means (if everything is setup correctly, eg --algorithm is right) that correct solution was not accepted because the network was too slow
to receive 'Stratum detected new block' on time thus it was not actual at that moment.

What work are you talking about? "the joint" answered the question I thought you were asking. If you don't see any "accepted" shares, then there is no work to be lost. I occasionally see "rejected" shares because they were stale. And when the pool is having problems, I see sometimes messages about shares being lost because I was disconnected for the pool.

When this message ("Stratum detected") appears, a new task is given to the client.

When asking the question I thought that if he was searching a solution to the previous task and didn't have enough time to find one, that part of work was essentially lost.

Now I understand that every single hash out of 400 or whatever kh/s the client can produce has the same probability of being the solution. And it doesn't matter if it is the previous task of the next one.

So the work is not lost.
