Have you checked the catalytic converter?

SES light on?

I'm thinking possible plugged exhaust. Try pulling out the O2 sensor and running it.(to test)

Would be the faster way to test for a plugged exhaust, and also the cheapest!!

have you check for compression? in all cylinders.
you said you replaced yourfuel pump did you make sure fuel pressure is around 50psi-60psi running/off? maybe falty pump.
any check engine lights? codes? is the timming correct?
good luck

This just sounds like a typlical ICM failure to me. Check this thread and see if you get the same impression.
