This sounds to me like a problem with the electrical connections in the multiplug sockets ,the previous problems were 3 yrs ago but check out that you do not have a siemans coumpter these are prone to weird and wonderfull faults .Normally once you start getting cam sensors and crank sensors then misfire 1/4 and so on this is a prelude to a faulty computer .
