Default 1997 SC400 Stalling Issues

Just yesterday I tried starting my sc first thing in the morning.
Turned the key, started up, then sputtered to a stall. Immediately restarted and drove about half a minute before it stalled at a stop light around the corner.
Started up again and drove it home, then to mechanic's where they checked basic fluids/battery/alternator, no issues. No fluids leaking, no odd sounds.
Drove for maybe 2 more minutes total the rest of the day without issue.
Went out this morning and again stall after start up.

My car is an automatic, 155k miles, runs perfectly, usually idles super low. No issues whatsever. The engine light and a few others come up when the car stalls so i will be taking a diagnostic test to see if theres an issue.

Ive seen similar issues but without the same cicumstances so any help, ideas would be greatly appreciated guys. im stuck driving my other car to work yesterday and today and passing on the highway in an Integra is more frightening than a nice V8.

Any help or guidance would be great.

Thanx and have a great day
Steve

Its at the mechanics right now for inspection and to run a diagnostic test. Fuel pump sounds good when I first turn ignition but would a bad ecu effect the fuel gauge? It just hit me today that I havent had to put gas in for about 2 weeks.

OK, mechanic state inspection and engine code diagnostic, no results. He said everything looks good.
Now im at a loss I guess. What else could this be. Seems like it runs fine the rest of the day cause the drive to the mechanic was uneventful.
Just first thing in the morning, car starts then immediately turns off.

Let me know somethings to check so when I pick it up these guys can check a few more things before Im left with a trip to the dealership.

thanx

Update,
had dealer check diagnostics, no codes. Cleaned throttle. Still starting at start up only in the morning. Runs great rest of day.
Turn car, turns on rpms go to about 1-1200, then drops down n stalls engine.
Also have an ac light that will blink every now and then but ac is working fine.
Please let me know if theres any tests I should ask the dealer to do to diagnose this pain.in.the *** issue.
thanx guys
