Weird WOT Behavior

As some of you know, I have a '01 SE/PP. The only "mods" to the
powertrain are 19* timing and a Ghetto Box with an Accel panel filter. I
run Valvoline 5w-30 synthetic oil, Nissan or Purolator PureOne filters,
MT-90 gear oil (thanks, Rick!).
Ambient conditions in Kansas City are about 10*F, 72% humidity, 30.5"Hg
(rising), and a 14MPH Northwind. This morning, I started the car, smoked
a cigarette, dusted off the light snow, and *then* drove off to work.
Ten minutes later, I was in second gear, engine at normal temperature, on
level ground, and snapped the throttle open to get around some traffic.
This was the first time I hit WOT all morning. At about 5000 RPM, it felt
like I had hit some sort of governor. RPMs fell off to 4800-ish, and the
engine pulled again to 5000, where the cycle repeated. It wasn't as hard
as a rev limiter, but I can't get over 5000 RPM at WOT. Maybe like a
severe ignition retard, I don't know. If I keep the pedal at 75%-ish, I
can keep wheezing the engine up to the mid 6k range, but once I hit the
WOT threshold, I lose a LOT of power. I tried this in second and third
gear with the same results (though I wasn't able to spin as fast in third,
that's about 80 MPH). The engine continues to growl, as it does at super
high loads in that RPM range, but I can't accelerate.
No check engine light, no electrical fluctuations, no other indicators of
something going wrong; I just can't accelerate over 5k at WOT. What's
wrong with my car? :'(
