96 Pathfinder starts but doesn't stay running

Hello,

 

First time posting here and just looking for some help with my 96 Pathfinder. The other day it randomly died at a stop light and turned back on right away, but continued to do that over an over again after a couple stops while driving. A bunch of lights came on the dash including A/T temp, oil, battery and brake light. Drove it the next day and did the same thing. This time I had a scanner plugged in and noticed the volts dropping from 14.5v to low 12's right before it would die. Later that day anytime I started it the car would run for a couple seconds and then die again. I thought it was the alternator so I bought new one and threw it in but the problem still occurs. I checked spark and fuel and they both seem to be fine(not 100% on the fuel though). Open the distributor cap and it seemed okay. Distributor is also pretty much brand new so I don't think there is anything wrong with it. Tried running it with MAF sensor unplugged but no luck. I'm guessing it some sort of air issue or maybe timing is off?? Just looking for advice on next troubleshooting ideas. Thank you for reading and any advice helps.

Even if the dizzy is new it is common it goes out. My last one went because the little condenser on the side blew and wouldn't let enough voltage to the coil. I think no continuity or high resistance means it's bad or something like that. id have to check the old one. The fuel pump moves pretty slow so as for now assume its good if its flowing. If it doesn't change with the Maf unplug temp sensor and if that still won't work unplug the throttle.

 

the NA VG33 ONLY requires MAF, Cam signal, Coolant temp, O2, and a throttle sensor to run properly. to a varying degree one of those can be non functional and it will still start no problem. every other sensor is OBD and emissions and doesn't affect tuning and engine performance. Unplug your primary O2 (post cats don't matter) and see how that runs. 

 

My bet is still the dizzy or its timing. it should idle even with both idles unplugged just not very well. 

 

EDIT: You won't even get a code for the dizzy if it's bad. I wasn't even getting misfire codes and the think could barely idle with out sounding like a Honda. sorry honda guys
