  1. No codes. Not losing prime like when cups have gone before.
  2. Mack MP8. I had this issue one weekend, on a Saturday. She’d start then immediately shut off or die. I put new batteries in because they were week. I cleaned connections on cables inside battery box. Not sure if I did it by bumping something during removal or tear down but positive push button breaker was kicked. I reset it while finishing up battery replacement. I don’t know why but I always check it when I’m in there. It started right up. started and ran no problem. I got home Wednesday afternoon. Got up early Thursday morning. She started the starting then shutting down within seconds again. This is were she’s been for a few weeks. I had a fuel line seeping. Fixed that. I changed the fuel check valve or pressure relief valve on the head. still doing same thing. I tried checking ecm, and module wiring. I tried a test ecm. I am leaning toward electrical but I am at my whits end. any help would be appreciated. Thanks
