There is a valve on bottom of the fuel filter for water drain. I would say Fuel Filter as a start to change. If that does help then I would recommend dropping the fuel tank and cleaning it out and a new fuel filter again and fresh fuel. Dispose of the old fuel.

Was it blowing any heavy smoke as this was going on?

Also possible the fuel regulator has gone bad. There is a shim kit you can put on there. But for the age a new one may be a better option. If blowing smoke it maybe and EGR issue. Not sure if on LBZ if they all had EGRs.

Last thought is clean the MAF sensor on the Intake.

Change the fuel filter. That is most likely it. How many miles on it?
If not, check for the rub hole in the intercooler tube, caused by the power steering lines.

Make sure the filter is on correctly, not over tightened and that the WIF is tight. Make sure it's not leaking at the bleed screw.

Could have a slight vacuum leak that shows up under load and higher vacuum.

Also, check that intercooler tube...
