I've heard of this resulting from a marginal rotor in the distributor. It's
easy enough to test, swap in another rotor and go for a drive.
As Randall says, full throttle puts maximum stress on the ignition system.
Higher pressures in the cylinders require higher voltages at the spark plug.
Your rotor may be withstanding normal spark gap voltage but as the voltage goes
up the rotor breaks down.
