Have a 93 saturn twin cam. After the car runs awhile it will die. After setting for a little time it starts back up and runs for awhile. It has some codes in it.19 crank position sensor fault. 27 soft flag- quick qdm fault. 53 soft flag- electronic spark control over max value. 48 soft flag- reference pulse error. 41 electronic timing error. How much of this can be related to the crank sensor. Not sure what some of the codes even mean. Help if you can. Thanks

I would start with the crank sensor.

Have the fuel pressure checked as well.

I can check the fuel pressure. Hope crank sensor not to hard to reach. Thought maybe filter when I was first asked about it. Looks like it at least been changed sometime. Do they have a port to check pressure. Maybe line after the filter. Seen on cars like 97- 99 before. Thanks
