No errors or anything in the log other than "test run interrupted"? That's a bit odd... If there are other errors in the log, knowing what those are would be helpful in figuring things out. Anything like "Object not found" or things like that? Do you have the "Stop On Error" option checked in Tools -> Current Project Properties -> Playback? If so, as soon as you write an error to the log, it will stop execution.
So... guess if you could provide screenshots of the logs that are showing this behavior that would help debug further. As NisHera mentioned, it does sound, a bit, like a timing issue... but it also sounds like object identification issues. If you have your objects mapped using properties that may dynamically change from run to run, you will encounter any number of errors that, if that "Stop on error" option is checked, will halt your test run. So, it MIGHT be that you will need to rework some of your mapping criteria to be a bit more robust.
But, again, the logs will tell more... please provide whatever you can.
There's always a reason. ;)
What tristaanogre and NisHera said about timing could be the issue, or if you are using coordinates instead of object names, those can be inconsistent from day to day on a different size screen or browser. Seeing the test log would really help us figure things out.
