No true Scotsman.
We need more information on specific persons that claim they stopped believing in God and then started again in order to justifiably make the claim you're making. Although it's hard to pin down what you're actually claiming. My best attempt is "A lot of theists who claim to be ex-atheists were actually never really atheists."
This seems to me to be making a most presumptuous psychoanalytical inference from non-existent evidence. Even if you knew of a theist who went under-cover, even, as an atheist and then falsely claimed to re-convert to theism, the inference to the "so many" is still unjustified.

"I know what you are thinking about,' said Tweedledum: 'but it isn't so, nohow.'
'Contrariwise,' continued Tweedledee, 'if it was so, it might be; and if it were so, it would be; but as it isn't, it ain't. That's logic." ~Tweedledum and Tweedledee discussing the finer points of logic
