Hello, my name is***** and thanks for your question.

Usually this is caused by the accelerator pedal, the internal sensors go bad. There is a slight chance it is a wiring or PCM concern. To know for sure you need a scanner that can monitor PCM data live and see if the signals are reaching the PCM at the time of the fault occurring. 95% of the time its the pedal.
