my first suspect would be the cat converter. if it is plugging up it will cause these symptoms.

Suggested Repair

Inspect the catalytic converter for plugging, which can cause rough running, severe power loss, and a no-start. Also repair the hole found in the exhaust pipe between the engine and the converter.
