The mprime's stress test will run until you tell it to stop. I don't think there's a built-in way to let it run for a fixed time period (that's its design - better make your complaint on GIMPS' forums).
You can try some shell scripting tricks to limit the duration it runs -- but it's a pity that I didn't build "sleep" command into the CPUstress image.
The log files are probably created only when mprime is running in normal mode (searching for Mersenne primes rather than stress testing) -- check the working directories in /tmp because I'm not sure.
