I would not rule out an odd software glitch where it could stop receiving input from the pedals or any other host of oddities. How often do we need to reboot our computers and phones?
Possible? Not likely.

It is impossible to get a false reading from an electronic throttle.
There are two sensors in the pedal, and one operates at double the voltage of the other.
So, say you are at 10% throttle, one sensor will see something like 0.83V, the second will be exactly double the first, 1.66V. If those numbers are even 0.05 V off, the computer will trigger a light, ignore throttle input and put the engine at idle. So any combination of a bad sensor, wiring short, short to ground, short to power, short between the two sensors, will shut the system down immediately.
