Car stalls but easily restart
Sounds like you have a either a vacuum leak or a cracked fuel line allowing extra air to be sucked into the carb fuel mixture. Make sure all small to medium sized hoses are well attached to their fittings and do not have any cracks in them.
My '92 deville fails to start after the first 2
Next time you have the problem check the fuel pressure, bet you have none. The fuel pump is electric and located in the fuel tank. These fuel pumps last on average about 100,000 miles, less if you run the tank lower than 1/8 due to the overheating it causes the fuel pump due to the loss of lubrication and cooling from the fuel it sits in.
How do I check vacuum system for 92 Cadillac devill climate control system?
This problem is most often caused by the air mixing valve (usually its actuator has stopped working - fails in the cold position) so I would start there. Not sure about a 92 - could either be an electrically or vacuum controlled actuator. You can check vacuum at the HVAC control unit with a vacuum tester.
What does the eror code e30 means
Code 30 means the idle speed control RPM is out of range.
The computer can not keep the idle speed in the correct range.
Could be the control servo, a wiring problem, or something like a vac leak.

New alternator new battery battery light stays on
take the alternator to an accredited auto electrician for a bench test
they are fairly robust but if it has an internal regulator , some circuit may have cracked or the brushes may be damaged or a terminal insulation could be dislodged.
