It might be the TPS, but I believe it is not.
I would start with cleaning the IAC.
Bad injectors may cause tough starting while the engine is hot as well.

Check your fuel pressure when the bog occurs. Check engine light on? Even if its not, see if any codes are stored. Might have a code pending if this started recently

The TPS also controls trans shifts. When mine went bad the trans would shift kind of hard. As soon as I replaced it the trans shifted smooth.
