Need help with opti

I have a 93 Z28 auto with 152k miles on it Im recently having problems with it
While driving it for 5 minutes the car stalled while going over a speed bump.I noticed the service engine soon light go on as soon as it shuts off my first thought was a bad opti.Any ideas what could it be the car cranks but will not turn on. Fuel pressure is 45psi i replaced the spark plugs, and ignition coil as well.

Did you try to flash the codes on the SES light? Car stalled, SES light came on - it would appear that scanning it for codes would provide the answer as to why.
