2.5 260 runs then dies out
I have a 260 efi horn motor. Fires up runs then dies Crank it and it fires right back up. If I put it in gear it dies instantly I just ran it a few weeks ago and noticed when idling in gear it seemed to be loading up by when I would take off it cleared up and ran great. Today I couldn’t even get it to run in gear. Batteries are new and fully charged, fuel pump and filter are brand new as well. Could it be the ACU ?

Put a fuel pressure gauge on it to verify it's maintaining proper fuel pressure.

I just cleaned the map sensor fitting in the air horn and checked the map sensor itself, It’s definitely not a fuel pressure related issue it just cuts out. I tested the stator as well and that’s all good. I have a bad feeling it’s the ecu. I’m going to send it out to Brucato to have them test it

Update. Sent my ecu to Brucato and the fuel pump driver is bad. So I ordered a new Brucato ACU
