Have a look in System preferences under "security".
_In Panther and Tiger there is an item that can be checkmarked "log out after xx minutes of inactivity"_.See if there is something set.
Another item would be the energy-saving options, where a time can be set after which the Mac will power down ( and maybe log out all current users before ) or go to sleep.
*Additionally you might try* an app called "Cocktail" ( +Panther Edition+ is Freeware ) http://www.maintain.se/downloads/panther.html , it it a mainteance and troubleshooting utility, which can check for troublesome caches,preferences and logfiles.
It is useful to keep a mac running "clean" or to fine tune certain settings and it is not as risky as one might think.
*Either way, I think your problem is related to some timers set in System Preferences.*
