I know you understand at this point it is a hard issue to track down. It could be a failing part but seems maybe is a wiring connection type issue. I would have a pin tension test done, at the throttle body connection, the ECM and the gas pedal. you may need to replace some terminals or even have stand alone harness built. I do this alot to fix these type of random issues with out codes or hard failures. I have not seen to many failed pedals on these cars. I have seen several throttle bodies and one ECM. Now I know this could get kinda expensive real quick. A less exp thing you could try at home is to disconnec the battery and apply a light film of dielectric grease to the connection terminals of the connectors at the throttle body/ecm and gas pedal connectors just in case the issue is as simple as a little terminal fretting.
