UFO hunters say the move is the latest in a series of cuts to the feed - all occurring when strange objects appear.
Alien enthusiasts claims the move is a cover up - although even they admit it could simply be a meteor.
The latest incident occurred on July 9 and was first reported by prolific UFO hunter Streetcap1, who uploaded a video of the incident to YouTube.
However, even he cautions the object could be easily explained.
'Remember a ufo is an unidentified flying object.
'This could well be a meteor or the like.'
However, he then goes on to say that the move is strange.
'What made it interesting was the camera cut off when the ufo seemed to stop.'
Other enthusiasts put forward theories including one who suggested in could be the Chinese space cargo ship Tiangong-1.'I have watched the International Space Station a lot over the last 6 years and I can tell you that this is not the moon, nor a meteor,' he wrote.
'It may be the Chinese space station cargo ship, called Tiangong-1, or the other one Tangong-2.'
The Chinese ship recently hit the headlines amid claims China may have lost contact with its first ever space station raising fears that it could career back to Earth in an uncontrolled re-entry.
The Chinese Tiangong-1 space station module was launched in 2011 and was expected to be deorbited at the end of its life to crash into the ocean or burn up in the atmosphere.
But there are reports China has lost control of the spacecraft, meaning it could crash back into the Earth's atmosphere, exploding into molten metal that could be devastating over inhabited areas.
The video is the latest in a string claiming Nasa cut the feed to cover up UFO sightings.
'They should be made to explain why they are cutting off public information and debate,' demanded one commenter.
Earlier this year a Nasa spokesperson denied allegations that NASA technicians deliberately shut down transmission when UFOs appear on the live video.
According to the spokesperson, NASA never intentionally shuts down live transmission to hide UFOs.
Loss of video is usually due to loss of signals from the ISS.
In November Nasa captured a bizarre horseshoe-shaped object on its live feed of the International Space Station before transmission mysteriously went down, according to UFO enthusiasts.
The footage has prompted debate among conspiracy theorists who believe the feed was cut intentionally as part of an alien cover-up being conducted by Nasa.
The mysterious clip appears to show a glowing blue object floating ever-closer to the ISS while rotating on the horizon.
The feed is then apparently cut for around an hour before it resumes and a much smaller white light can be seen in the distance.
Conspiracy theorists say this may be the same craft that has since moved away - dismissing the idea that it could be lens flare or even the moon.
The 'craft' was spotted by Scott Waring, who posted it to UFO Sightings Daily and wrote: 'I saw a UFO at the space station.
'It was diamond shaped and it seemed to be changing its shape, but I think that's due to it moving ever so closer to the ISS.'
He claimed that shortly after the sighting the screen turned blue, which is Nasa's way of attempting to 'hide it from the public'.
The footage was then sent to Tyler Glockner of popular YouTube channel secureteam10, who uploaded the video alongside some of his own narration.
Speaking over the footage, he said: 'When you play this footage quickly, it looks like the UFO changes its position.
'When we first see it it's more on its side, but when you cycle through the footage it seems to be manoeuvring more on its face.
'It's definitely another interesting find and once again directly after it appears NASA cuts the feed.'
He later added: 'The only time when the feed tends to get cut is oddly when these UFOs appear.'
