1992 Olds 88 Royale Stalling

I have a 1992 Olds 88 Royale that will stall randomly, usually while coasting at low speeds or coming to a stop (it does not stall at high speeds). I will then have to leave the vehicle sit for awhile (because it won't restart) and come back to it, and usually then it starts right up. Sometimes I will park the vehicle after it has been running fine and come back to it and it will not start. The outdoor temperature or the amount of gas in the tank does not seem to matter. The vehicle has its oil changed regularly, spark plugs and wires changed 1 year ago, IAC changed (in an attempt to fix this problem) about 1 month ago. The first time I checked the computer for error codes (yesterday), it gave me code 17 and code 58. I then cleared the codes and checked it again today after driving the vehicle, and code 17 is now present again. I know that code 17 refers to spark reference circuit, but what exactly does that circuit involve as far as components? Right now from my research I have the following components as possible problem areas: crank sensor, cam sensor, oxygen sensor, MAF sensor, throttle positioning sensor, ECM, and ICM. Any and all help would be much appreciated! Thanks alot!

Code 17- Crank signal circuit (shorted) or faulty ECM

Code 58-PASS key fuel enable circuit

my car was doing the same thing now it wont start at all i got all new parts so if you get it fixed let me know i got codes 42 and 58

try cleaning your maf sensor with some good electrical parts cleaner it might just be really gunked up like mine was
