The bad connection might still be between the 68k and the CPU socket causing these failures?
get a big fan from somewhere, tabletop, stand up fan etc and point it at your amiga and see if that fixes it. I had one A600 that would crash on me when it got too toasty and as soon as i cooled it by pointing a household fan at it it would chirp along quite happily. Could never figure out why it got so hot, i think it was just the internals of the cpu that for whatever reason consumed too much power and got too hot.
