Hey Scott==Check the cat convertor. Put a vacuum gauge on the engine and see what vacuum you have at 900rpm.It should be about 18 inches. Then rev it to 3500 and it should not drop over about 5 inches. If it drops to 8 or9 inches and stays there at that rpm, the conv is plugged. GoodluckJoe

Sometimes this condition is caused by a dirty fuel filter.

It depends on what you mean by "loses all power". If you mean the electrical system stops working (i.e. engine quits, no lights, etc.) then it could also be caused by a dead alternator or battery, broken alternator belt, bad electrical connections, etc.

If a Volkswagen Jetta loses power while driving uphill, one possible explanation is that the mass airflow sensor has gone bad. Another possibility is that the intake manifold could be clogged. The only way to know for sure what's wrong is to take the car to a mechanic.

One thing that could be wrong with a 2013 Chrysler 200 when it loses power and smells like rotten eggs is the catalytic converter needs to be replaces. When a car has a rotten egg smell, this is usually the cause.

Sound like a transmission problem. Check your fluid first.

A 95 Toyota Corolla engine that loses power when idling can have a number of different things wrong with it including clogged injectors, a dirty fuel filter, or fouled spark plugs. Performing a standard tune-up will often resolve this issue.

If it lost all power it could be the battery connection.
