2006 Mazda 6 V6 started choking down sputtering, and minor backfire. No power at all

It did show those same symptoms a few weeks ago but then started running good.

No check engine lights are on.

Mechanic could not find anything wrong. He did say the catalytic convertors are not plugged

It only does it when the engine is warm so apparently they only checked it with cold engine.

A few months back all coils were replaced and a full tuneup

Thinking about take it to the dealer

Was there ever a solution found!? 05 Mazda 6s v6. Fine when cold but after warming it sputters backfires has NO power around 3000 rpm.
started doing this after the battery in it died after running out of gas and i jumped it to get going.
it’s been doing it since then.
I added injector cleaner after running it out to avoid clogging my injectors.
when it is at idle warm it idles at 1000rmpbut surges slightly.
