Car starts runs for an instant and dies
Car is a 98 LS 400 with 192k on it.
A couple of months ago the car died while driving at 40 mpg, like turning off the key--no warning at all.
I tried to start it several times and it would run for a few seconds, idling roughly and then die.
After about the fifth time it started and continued to run with a smooth idle just like normal. I let it run for a bit and drove home 10 miles at 70 mph and everything was fine.
I haven't driven it much since then, maybe 50 miles and no problems. I have been running it a couple of times a week to keep the battery charged up which leads to my current problem.
A couple of days ago I was in the car letting it idle and after a few minutes I noticed that the idle had dropped from 700 to about half that and a few seconds later it just died.
I have tried to start it since then with no success. It cranks fine seems to catch for a second and dies.
Any help would be appreciated. I have read other posts with similar symptoms but none quite like this.

What are the error codes?
If you don't have a reader, units like this one are good basics:
