That sounds like your car may be going into limp mode. Can you post all the codes? Maybe the computer is going out.
I recall a few P300, P301, P304. My car has been in shop over a week. If computer is that expensive to replace?
Yes those are miss-fire codes. https://www.obd-codes.com/p03- codes

P03xx means misfire in cylinder XX. If it' P0300, then you might have an "Oops, I didn't fire, silly me" plug. They will rapidly cause your catalytic converter to go boom. [Not literally.]
You figure out what was wrong with you Honda
I really hate it when people post the problem but not what they found out caused it. I'm having the exact same problem.
