Hi there. From the description you have provided, driving your vehicle for about an hour, lost power, powertrain malfunction indicator illuminated, later the powertrain malfunction indicator and service engine soon light illuminated, is difficult to estimate the cost of repair. Diagnoses needs to be performed to isolate the failure first.

It could be a faulty APP (accelerator pedal position) sensor. It could be a faulty throttle position sensor at the throttle body, which in most cases requires throttle body replacement when electronically controlled. It could be low fuel pressure caused by a faulty fuel pump. There are many other possibilities as well. I recommend having your vehicle’s powertrain malfunction and service engine soon light illuminated be diagnosed and repaired by a certified technician, such as one from YourMechanic.
