When the problem is ongoing, if it cranks good, have a helper crank it while you check for spark at the plugs, if everything is hot, wear gloves. Check proper fuel pressure and fuel injector pulse.
I'm especially interested in the fuel injector pulse. If your losing rpm signal, there will be no fuel injector pulse.
How long since overall tune-up? Any applicable trouble codes? Your obd1 so checking trouble codes should be easy, as long as your mil lamp works. There may not be any codes, I don't know? I can only help with testing, you have to do the testing.

you need to pressure bleed the system, or you can fill the brake system to over fill as it needs to be over the pipe for the clutch line. and keep it there and pump and bleed the line, but before pumping undo the bleed screw and put bowl uner to catch fluwid and fill the line up till it runs out clear with no bubbles. then tighten the bleed screw. then fill up and pump pedal, the re bleed. should be done then, pressure kit doe this all in one just hold clutch down and undo the bleed screw let air out etc then tighten up. and its done. used for doing the breaks as well.

To start, take the vehicle to a dealer and ask them to screw an oil pressure gauge into the block hole and check your oil pressure whilst idling and while driving it.
I have a 1993 and it does the same thing, but the problem is only the gauge itself.
If it is actually having such oil pressure fluctuations, you may have a defective pump, a clogged pump filter screen, or a clogged oil filter.
God bless your efforts.

the Fuel Pump relay and fuse is under the plastic cover under the hood at the firewall on the passengers side.

Assuming you are correct, then the only two things still needed are air and compression. As long as the air filter and air intake is not completely clogged, you have air. Perform a compression test to ensure that there is sufficient compression to support combustion.

You should be able to look down the throttle body and see into the air bypass chamber that the IAC uses to divert air around the throttle blade. Look to see if the pintle is all the way out closing off the flow of air. When you turn the key on you should see the pintle move back and allow air to move through. If the pintle is not moving that it may be stuck in the bore. Especially if there is a lot of carbon build up in that passage.

Sounds like you need a new battery, but just in case take the battery to a place like Autozone or another car part place and get them to test it. It's usually free to test.
