K-5 Sensor temperature overheat and fail

I tried different memory cards and left the camera off for days with the battery out. Thankfully I had the K-x to carry on with which I did for the rest of the holiday. No matter what I tried I could not get the K-5 to take a photo. The camera itself behaved normally until you took a photo, whereupon no pic would be taken at all, with the same overly long exposure.
Once back in the UK, after a couple of months I managed to get the camera to take some photos, but they had a weird cast in horizontal bands. If I did Live View the camera would soon just show vertical coloured bands.
Yesterday, after a leaving the camera for a few more months I got it to take normal shots for the first time since it played up. Today I took it out and managed about 30 pics before it failed with it multi-coloured stripe issue.
Tonight I took a few (they were fine) and then tried it on live view and within a few minutes the red thermometer had appeared and the camera failed. It seems to me that sensor overheats too quickly. In a few minutes the EXIF value was 51c. I am on the latest firmware and have tried different lenses.
Has anyone else had this sort of behaviour? Is it possible that the sensor's ability to keep itself cool could somehow fail? The camera has never been dropped and nothing seems loose.
Sadly from what I see K-5s go for I don't think it's worth repairing.
FWIW on one of our trips we went right near the Pentax Hanoi lens factory. Strange to think that the 16-85 I was using was almost back at its birthplace!
