I had exact same problem, they found it to be a hairline crack in the distributor cap that could only be seen under ultraviolet light. Hopefully that may help

TPS possibly - when it's doing it, unplug the TPS and see if it changes anything - if it DOESNT change then your TPS is bung.

I'm assuming it doesnt have this problem when cold ? perhaps could be as simple as air-bubbles in your coolant system !! once thermostat opens the bubbles find their way round to the IACV (etc) and can cause similar problems.
