if the car does it in the drive way,,,then a connection getting hot and then cooling off could do it....a bad solder joint...possible...I don't know if there is a relay involve .........is that the only thing that cycles,,,,,,how about the radio or interior lights........do the gauges shut off and come back on...when did it start...hit anything with the car...disconnected the battery for any reason...what's the last thing that was worked on in that area...is the engine running when this happens..if not to all the above, then I would the cluster and check for a solder joint that doesn't look nice like most of the others.......if you don't see one...get back to me.......joser
