Had my T/A out the other day. I drove it for an hour or so with no issues. Went to make some hard so with and the power just disappears around 4k. It keeps pulling but power isn't there. I did some data logging on it, but when I went over the log some of the sensors were table topping. Rpm, IAT, ECT maybe a couple more. Still on the 98 pcm.

Just a stab in the dark here but check the fuel pressure underload. You could also post the log.

I had the same problem and it was my fuel pressure.
