[V8] V8 cutting out at about 1800 rpm

[Alan Kramer]

The hall sender in my case would die when the motor got warm.  It would 
start and run the first 10 minutes or so just fine.

Then if you tried to accelerate the car would hit around 2k RPM then would 
start running on 4 cylinders and would if you let off the throttle it would 
fix itself until the next time you hit the gas .

The car didn't throw any codes, and everything else tested fine.

Sounds exactly like his problem to me...

Only thing I can think of right now is that maybe the ECU doesn't like the 
hall sender getting "unplugged" while the car's running...but if it starts 
w/o it, it will deal with it just fine.
