93 ZJ Engine Stall

I went to start the Jeep a few days ago and when I turn the key and it cranked over for several seconds then started and ran. I let it idle for 10 or 15 minutes and then I put it in reverse and it died. I tried to restart it again and it just kept turning over but no fire. I let it sit 24 hours and then I went out there and gave it another shot, only this time it fired right up with a loud misfire. It ran after the misfire and I let it idle again. I put it in reverse and it didn't die, I put it in Drive and it didn't die, I put it in reverse again and it didn't die, and then I put it in Drive and it died.

I know I have a faulty fuel pressure regulator which is causing the long crank. But now I think it's starting to fail completely because my idle isn't correct and it's stalling and not trying to restart after it stalls. If it's not a fuel related problem then it would be an ignition problem but I just replaced the spark plugs and those spark plug wires I bought back in June 2018. So that would boil it down to the ignition coil and the distributor right?

 

The first thing you want to look for are any codes sent from the computer,.

 

I'm going to run the DTC codes with the key ignition. I'm also going to follow these ignition troubleshooting steps from this website here at this link...
