Many things but you might start with a clogged catalytic converter.
Gravity! We fight that loss of power by using more torque.
What would help would be an articulate question. Does "lose power" mean a loss of voltage/current, or a loss of engine power (horsepower/torque)?
Common cause for this type of malfunction is improper timing. This is dangerous in these engines. I suggest you take the vehicle to a competent mechanic immediately.
Check the catlytic converter for blockage

Reactance certainly causes loss in a transmission system, but I^2R or resistance losses are greater.
Check power steering fluid first, then take it to the shop if it is full.
Probably the increased load on the engine caused by the power steering pump.
There are several causes that can cause a generator turbine system to lose power. The most common cause is a lack of fuel.
