Been chasing this problem for a couple of months now and running out of ideas.
The first time I had been driving for a bit (15 minutes or so) and was headed back home, in third gear, A/C on, and rolled into the throttle (60% or so at about 60mph). The car was making boost (10ish psi) and then it stumbled pretty hard. I lost power, but when I backed out of it and blipped the throttle I could hear the SC whine, at this point all the gauges except the boost gauge were dead, odo was all dashes, speedo and tach at 0. I made sure it was in neutral, flipped the ignition off and tried to restart it while I was rolling. From the sound of it, it seemed like the engine was struggling to start (I traced this to the weak economy battery the previous owner had put in the car), but after a second or two of cranking, it fired up. It drove normal the last couple of miles home.
I removed the integrated radar detector that didn't work and all of it's associated wiring. I also re anchored the ECU (it wasn't secured in the plastic holder) and regrounded it.
Took the car out for a test drive, wasn't even a mile from my house and it died, all dashes on the odometer, and dead gauges just like before). I recranked it, it fired up easily, and I motored along. I noticed now however since the radar detector is gone (it was in the way of the light), the theft light was blinking a code at me. Code 16, which comes back as the PATS system can't see the ECU. I was informed by the previous owner that PATS was disabled, so this could be the source of the code, not sure at this point.
I drove around a bit more to get some heat in it, at one point when I was pushing it a little bit it did the thing that it does where it drops power so hard it feel like I jammed on the brakes. I suspect these are two different issues.
Anyway, I got it home and was laying down boards to get it in my shop (it drags the exhaust otherwise) and it died just sitting there. In fact, it died two more times before I was able to get it the last 15 feet into my shop. While trouble shooting it I had it running in my shop and it ran (idled) fine, no issues. Not sure what to make of this. The car has an SCT flip switch plugged into the service port of the ECU (which I noticed today is a reman unit). I don't really care for these type of programmers, however I don't know if this could be the source of my issues or not.
