There are a couple of possibilities here. Check fuel pressure while driving the car. If fuel pressure is below specifications, or drops the closer you get to 50 mph, the fuel pump may be worn out, fuel pump relay with burned contacts, possible clogged fuel filter, or clogged injectors. Check the air filter as well for clogging. If all of these components check out, observe if the engine pulls strongly at lower speeds, but going up hills where more power is needed. If not, have the catalytic converter checked for clogging. Clogged catalytic converters are the result of unburned fuel, oil fumes, or high-sulfur content gasoline leaving the engine. I would recommend an one of our inspections; car is not getting enough power to diagnose this problem, get an accurate assessment of damage and cost estimate for repairs. YourMechanic can dispatch a mobile, professional mechanic to your location for this repair. Contact us to request this inspection and to schedule an appointment.
