So, yesterday I fished the wolfsons childerens hospital TX out of palatka, fl. My partner and I decided to make a one way 45 mile run up the St. Johns. We got about half way running around 75 when the motor shut down for a split second. I thought I hit a manatee. We stopped looked at the prop lower unit didn't see anything. I restarted and off we went. I got to about 50 and it would intermittently die but never die completely. When it would die the gauges would go dead then come back on. The third time it happened I lost all power, trim ran slow and the starter would click when I turned it over like the battery was dead. But, the fishfinder would not go dead and showed a steady 12.8 volts the entire time I tried to start it. I opened the rear compartment and checked all the connections nothing was lose. It finally started again and would intermittently die. Then, as fast as it started it went away and didn't do it the rest of the day ran great. This is in a 1994 2003 with a 2005 225 Pro XS. The mercmonitor never showed any alarms. Although when it would die the whistle would sound but, it sounded sick and lasted a millisecond. This is a MAJOR reliability problem and I cannot take this thing out if it might quit and leave me stranded somewhere. Being an old ass boat there are several splices in the ignition harness in the back compartment. I didn't make them they were there when I bought it in 2007. Plus I run a newer motor now, I was thinking of buying a new 14 pin ignition harness and key switch and starting there any one ever seen this before?
