Throttle problem

So I have an issue where ocassionally when im giving it alot of gas the car will pick up but then completely choke and then if I let my foot off the gas it will be completely normal. I let it pass last year when I was accelerating up an on-ramp, but this has happened 2 times this past week. Its a little dangerous if you have to merge and the throttle dies...which is what happened again today.

Any idea what could be happening? TPS getting bad or something? Maybe the line getting choked somewhere? I dont get any engine codes, so it leads me to believe something is clogging the fuel line somewhere.

exactly whats happening with me

tps doesnt seem to be the problem

im thinkin either sparkplugs/wires or the ecu itself.

My TRAC light and Check engine light pop up right when it happens. I gotta baby the throttle or else it chokes up and starts surging not gaining any power

Its something I would really like to figure out
