Mine does the same thing sometimes, but mines a manual. I notice mine only does it when the rpms drop below a certain point. My rpms sometimes bounce a little when coming to a stop. When it goes below a certain point, the blower quits, but as soon as the rpms go above that certain point, the blower comes back. My theory is that the computer is shutting down accessories to try to keep the engine running. Either that or the relay that turns the blower on once the engine is running ends up believing the engine has been turned off and it loses power momentarily.
