That tach symptom is a definite indicator that it is not fuel related. 
Several of us are chasing similar problems, and to my knowledge no one has yet found 
the definitive "smoking gun" evidience to prove a cause/fix.
Yours is unique in that full throttle will recover. My car would eventually 
die and need to be re-started, after which the computer re-boot of shut-down 
solved the problem.
