Tunze 6105 randomly stalling

Hi, I bought a used Tunze 6105 a few weeks ago on RC and its working has been random. I ve cleaned it, connected it to different outlets/surge protectors etc, but i may run anywhere from a few minutes to hours and then stop. The power block seems fine (18 V resistor in). No similar experiences on the internet. Right now, it is not really running reliably for more than a couple of hours, no pattern on when it stops. i ve used it both with a controller and without.

Any suggestions/experiences on this may help.
