stalling

New to the forum and excited to see all the good content from the members!

So... I could use a little insight!

I have a 2010 Clubman S that will not stay running. It starts up and runs perfectly and then just instantly shuts off. Sometimes it will run for 30 minutes sometimes just a couple. Sometimes it will fire right back up but other times it needs to sit for 20-30 minutes. Also, sometimes it will blow fuse f7 (which I believe is related to the AC) and then stall but not always the case.

I have the following codes.

P3149
P3152
P3155
p3158

(High pressure injection valve highside control low voltage) for each cylinder

Prior to issues I did have the battery disconnected for about 2 weeks.

I'm thinking I may have a short to ground but thought I would see if I could get any input before starting that hunt!

Thanks
