Ok so I have a 1988 chevy beretta 2.8l multi port fi, and just a couple of days ago it just stalled at a stoplight, it didnt shake or jerk or anything before it died it juat smoothly cut off, for a second I didnt even know it cut off, i dont think it has anything to do with the battery cause my music and everything was still playing, its done this a few time, some of the times it would start right back up other times it wouldnt start until a few moments later of trying and pressing the gas pedal to get it started and when it did start after trying all of that it would kinda start rough, I need help on where to start!

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

When you get one of these you need to be ready to check what is dropping out WHEN it won't start if it still cranks. Gotta be ready with spark tester and fuel pressure gauge at the ready. Dang, if it starts right up things are going to test fine.
If it cranks normally it's not the battery. I think 3 things can shut these pups down, crankshaft position sensor, wiring at coil pack and some the oil pressure switch if failing.
Gotta catch it. Try for codes but doubt it will say much for an 1988,
