RB25 Help in Socal

[951's 330i]

Ok so i was wondering if anyone knew of a good shop that can take a look at my car. Its a RB25det and for some reason, it dies after being on for a while.

Dont know if its the MAFS since it wont start with it on or off.

THought it was this sensor i found unplugged under the IM but that didnt help.

Think it may be the coils but not sure of that either. And dont know if its the ECU either. I tried reading the ecu but i had no luck with it really. (Noob at most of this stuff)

Any shop that you can vouch for would be thankful. Im located in Socal corona, so anything by there would be great. Money is tight right now so thats why im not just out and changing the parts i think it is.

Thanks

what do you mean that it wont start with or without the mafs ?

As in like, before now, it would start without the mafs connected but just wouldnt pass 2kr.p.m. Now once it shuts off thats it, it wont start with the mafs connected or not
