This is going to be hard to hear or see, but this is what happened the last time I drove my car. My foot was steady at about 40% throttle, the car just started hesitating randomly from about 2500RPM. You can see the RPM stop and go along the way before it hit 7000, this was with my foot held at the same exact situation.

Here are some things that might be helpful

#1 Cruise Control would cut out on its own
#2 On the OBD II logger, calculated load/throttle position/MAF reading all went to zero as the engine hesitated
#3 It happens at random times, AC on off, VDC on off

The problem also seem to occur more often at part throttle, less likely on full throttle.

I wonder if an animal ate some part of the wiring harness because my car sat at my friend's house for two weeks while it was getting the hitch installed.

I ran without the brake light fuse, problem was still there. I adjusted the brake light switch, so I don't think it is that. Can OBDII tool detect clutch position?
