My Crossfire is not the SRT version. It's the normally aspirated V6, and I'm sure the previous owner left the car completely stock.
I'm still leaning towards the fuel starving possibility, i.e. perhaps the fuel pump, and/or the filter, or something else causing the engine to starve at around 4,200 RPM. But it could be an electrical issue...
It's a bit odd that it happens only very near the 4,200 RPM mark, and at no other time. And other than a very minor idle misfire, it runs great. If I have time this week, I plan on taking it to Autozone so they can check the computer codes. It would be a lot of simpler if the check engine light flashed, but I guess I'm not that lucky.
