If it is the pump, it is easily accessed from the front of the tank on
our 88 Cherokee. No need to drop the tank. When I see those die, they
usually up and die. They don't give much warning from what I have seen.

Also check the catalytic converter. We had exactly the same symptoms
in an '84 Audi 5000. Had the car in the shop for over a week. Even
had the factory rep out to look at it. Finally, the shop foreman
removed the exhaust pipe behind the muffler, and the problem went
away. Cat converter clogged.

The way to test that is with a vac gauge.

This site has a good writeup.
