This sounds more like a vacuum leak of some kind. Follow the Factory service manual for setting the idle first then you can fine tune it in the software.

I'm not sure what you mean exactly....a cable actuated throttle will not be intermittent.

Sounds like a TPS issue, datalog, if the TPS reads zero the same time as when your gas pedal stops working, it's the DFCO kicking in, resulting in a no fuel condition, but it shouldn't take a minute, in fact, it should be just jerky, unless if you have a faulty TPS that feeds the ECU 0V on the throttle signal line.
