1996 Es300 Starts Up Then Dies Immediately, P1300

I drove my car today for a bit, and it kept shutting off. I was able to restart it fine, but then after a few minutes it would shut off again. Repeat about 10x

Now my car will start up but then it shuts off immediately!

I also have check engine light code P1300, but no misfire codes P03xx (misfire in cylinder x)

This is the only code I have besides the oxygen sensor that I already knew about.

I got new spark plugs about 6 months ago, maybe 5000 miles ago and yes I used the proper twin-ground platinum plugs

Where those Bosch plugs? if so they are garbage.... also what are the other Oxygen sensor codes...You still may have a missfire code....Sounds to me like a bad igniter...(coil Pack)

The oxygen sensor code is P0135, which I've had for awhile

The only codes I have are P0135 and P1300

Yes I used Bosch plugs (4301) and NGK wires (the blue ones). Nobody seems to carry the twin-ground NGK plugs, I think the part number would be 3452

Surprisingly neither company makes coils

But why wouldn't it throw any 'regular' misfire codes (P030x)? Before replacing the plugs, the check engine light would blink sometimes, and I had most of the P030x codes, including P0300, but they never came back after replacing the plugs.

UPDATE:

I think the connectors to the ignition coils are no good. I know the one for cylinders 3 and 6 (located on #6) is no good. I saw a little white sheath sticking up from that connector. I pulled it and off and the two wires were kind of hanging loose, not tight as they should be. I pried the wires back into place and then snapped the connector back on. I successfully drove it about 6 miles (3 miles each way) with no further drama.

I hope this is what it was. It would make sense because it doesn't necessarily mean that any coils or plugs are bad (hence no P030x misfires)

Sorry I forgot to take any pictures, but I can't go back and take any now because if I take the connector off again it might not go back on! Now, how would you replace those connectors by any chance?
