Restart trouble after re-assembly

ps. thx for the note re. TPS and AFM - I was thinking that perhaps if the DME was getting weird inputs from the metering side of things, inputs that it doesn't look at when the engine starts, it might shut down when it gets out of "I'm just starting" mode and into "let's go!".

The ECU needs the input from the reference sensors to start and stay running, I know you replaced the sensors but it would still be a good idea to do the test procedure on them when it dies and wont restart. If the test is good then you might look closer at the ECU. if the test fails then you have a wiring issue.

OK, that all makes sense, thx.
After a quick tinker this morning, I'm going to look harder at the DME and connector. AT first the engine didn't start. And then it started. But the significant thing: while it was running, I managed to get the engine to die just like it has been, by slightly wiggling the DME connector. I guess it doesn't rule out a problem elsewhere in the wiring, but that area looks pretty suspect now - especially as cleaning it up before made such a difference.
I opened up the DME connector and the inside looks in good shape - all the insulation is intact, no corrosion or dodgy spliced wires visible. So on to the DME next.

...and a couple of days on, it's looking good. Started every time, no mystery engine cut-outs. Running well, other than an occasional slight rise in idle speed to about 1200rpm. (So maybe I still have a slight vacuum leak.)
