Will take the harness off clean all grounds and reconnect
I was talking about
Service Bulletin DSB-1053
To dampen vibration to the ECM/fuse block bracket, install Briggs & Stratton Service Kit (Part No. 847337), which includes a new fuse/ relay block cover, ECM mounting bracket, rubber isolation mounts, and mounting hardware
It was in the Repair Manual pdf pg 8,
I have played with the harness some, but not removed it or cleaned grounds, I did take out all fuses check them and put them back in 180 deg. Yesterday i was able to cut grass for 1 hour again without any issues but I do not trust it.
