As Tabetha said could be a stuck relay or possibly a faulty fan switch.
When the faults happening again, unplug the fan switch. If the fans cut out it will be a switch fault. If they stay on, its likely to be a relay issue.
As for only one working, when the fans are in check to see if you have voltage to the fan that isnt working and also check for a good earth.
If both elements present then it may be a fault with the fan itself. if not you've got a wiring/power/earth supply fault.
Personally I would just pop a new fan switch in and rewire the fan circuit using 1 relay and 1 fuse for each fan. A lot more reliable!!!

Ok well it won't be that then, usually you have to change the thermostat (stu @ msd sells them) as the fans cut in all the time, but that's obviously not your issue, hope it's just a relay and you get it sorted out.
