It is rare but it could happen

You need to get it scanned for trouble codes.

32/33 Lb.ft for the connecting rod Bolts. For other units kindly use conveters

check your starter sometimes the solenoid gets stuck if this is the case you will need to replace the starter.

Your car needs to be hooked up to a code reader/computer to read the specific error code.

possible the o2 censor but finding the right one some cars have more than one you need to know which bank and if it the front or rear sensor your local dealer should be able to tell with computer

Without knowing what the fuel pressure is, no one can say for sure. You'll need to check that. If you find there is a fuel pressure issue, you'll need to isolate the cause (wiring, connectors, pump relay or the pump itself). You will also want to inspect/examine the intake air hose, filter & vacuum lines to eliminate those things as possible causes. Additionally, you might simply have a throttle position sensor which is malfunctioning/going bad. You'll also want to scan your OBDII for any trouble codes which may have been set and which could help narrow down your search for the cause.

b-alarm 10a fuse located in engine compartment fuse box,fuse gives power to dome and map lights.

Your car may have an "immobilizer" which is part of the security system. It will start and stall if someone uses an "unauthorized" key to start it. In other words, a key that was not programmed by Hyundai or the dealer to run the engine. This happens if you had repairs done and immobilizer was interrupted and all keys were not present for programming and you're using one of those keys perhaps and sometimes it just loses its frequency. These systems often have a different frequency each time they're coded so all keys must be programmed at the same time every time. Sometimes the immobilizer coding process is simple and included in the owners manual...NOTE: this could be an indication of a bigger problem if it keeps happening.
Good luck
