Also check MAF sensor to see if it's dirty. It has major effect on air/fuel ratio. I say air/fuel mix too lean is your problem but why is what we need to determine. OX sensors also possiblity? Or some air leak after throttle plate.

Crank sensor only decides spark or not. Why would stepping on pedal change what crank sensor is doing? Crank sensor has no input from other sensors. Now if this problem were random and unrelated to other actions by operator then it could be considered.

The TPS would be the sensor to suspect with your symptoms.
