Something like this sometimes stems from a sensor(s) falling out during the indicated range, that is the signal falling out. Such could involve the throttle position sensor, mass airflow sensor, or perhaps sensors involved in advancing ignition timing. EGR system malfunctions are also a possibility. Typically a real time automotive scan tool, which is viewed by the mechanic during the "window" of misoperation, would yield answers as to what is going on. Key engine operating parameters are viewable on such a tool. What I would suggest is you request an engine loss of power diagnostic. If you request that diagnostic, the certified mechanic will get this resolved for you.

My car acclerates fine but is hard to accelerate after driving for some time, even while flooring the gas pedal.

If the poor acceleration is intermittent, that suggests a cause involving an electrically controlled component including sensors that send data to the PCM. To diagnose this, a real time scanner is applied to view actual engine operating parameters during the...

The "hold" light keeps popping up on its own and it causes the car not to get out of third gear.

Try holding down the "HOLD" button for about 5 seconds and this should correct the problem. If it does not, you may have a computer issue that will require diagnosing with a scanning tool. In this case I would recommend...
