Hello - the loss of power you are experiencing could be a failed throttle position sensor, or a clogged catalytic converter. Either of these will reduce engine power, and cause the lack of performance you are seeing. I recommend a loss of power inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
