Random multiple DTCs?

Every 3-4 months I seem to throw several codes. Normally I get both high/low opti codes along with a couple other random codes. Last night it happened to be the Injector Circuit and EE Prom Error codes.

I will be starting the car, it catches, and then it just dies. Crank it for a couple seconds and it starts up showing all the codes, and to top it off the A/C stopped working.

I drove around for a bit, and then I stopped and pulled the pcm fuse (reset the codes). Started it back up, and the car ran perfect.

Anyone else experience this "hiccup". Not sure what to call it...

I had this same problem one night. It was the first night I tried my new changes I got from PCMFORLESS. I tried my usual long stright road in the country and mashed it. I got 6 different DTC at that point. Car ran like a 2 cycle dirt bike with a fouled plug. I stopped and pulled the PCM fuse and all was fine after that. I contacted Bryan and told him what happened. He deturmined by the odd codes I was getting, (I believe they were 51, 88, 90, 91 and I can't remember the other two) that it was just a bad flash. Sure enough, I re-flashed w/ the same program and all has been well since. If you have the ability to re-flash your PCM, do try it, as I am sure it will work.
