What really throws me off is why the ECT drops down and slowly climbs back up. I thought it could be the ECT sensor dropping out and some how causing the EEC to do weird stuff with the timing. I tried pulling the connector while the motor was running, but the datalog just shows the ECT staying at the same position it was in. I bought a new sensor to try, but I haven't put it on yet.

Re: Analyze my Datalog. . .tell me what's causing this
I just replaced my ECT too. Do not buy the cheap plastic one. They tend to go bad after a year. I have gone through two of them already. I now have the original Borg Warner version.
Another food for thought, If the EEC power relay was on the fritz then it could cause what you are seeing. Since you are monitoring the EEC while this is happening, the EEC loses power, but the Tweecer plugged into the laptop is supplying the minimum voltage. The PC will not be able to supply the full current and things begin to drop off.

I've got a DataQ that I can tap into the EEC power circuits. I can use it to datalog in the WinDaq software -- that way, I can see if the power relay maybe causing an issue.

Re: Analyze my Datalog. . .tell me what's causing this
Another thing to check would be the MAP sensor. There is a spark multiplier associated with it. If the BP is real low it applies a multiplier of 0. Anything multiplied by 0 is 0.
Maybe, Maybe

Re: Analyze my Datalog. . .tell me what's causing this
I don't remember, does the ECT and distributor harness run through the same leg of the engine harness. Maybe there is a loose wire as you said.
Also, kinda off the wall, but my Cobra would do the same thing when I first put my switchable chip in. The switch was not fully secure and would bounce around and the ignition would cut out for a split second over bumps. Only occured 2 or 3 times but it was an easy catch. I know you don't have a chip, but maybe your Tweecer wiring or connection.
