Im struggling here. I have a 4.3l 430A 1992, I put it on the lake and she runs like a raped ape for about 10 minutes, then It starts to loose power and die, all within about 5 sec this happens. I start it back up and take off again and within about a min it will do the same thing. I was trying to get back to the launch and as im heading back its progressively getting worse. Each time it dies it gets harder to start back up. This has been the same issue the last 3 times I have had it out. I replaced the Fuel pump, filter, fuel lines,plugs, wires, rotor ,cap, coil, thermostat, impeller, completely cleaned and disassembled the carb, checked the fuel tank vent , checked the pick up tube in the tank, new fuel, checked the anti siphon line and tested the emergency kill switch. All this and still dies off on me. The temp reads 140 degs and when feeling the motor, everything feels luke warm like normal running temp. Its almost like the some thing it cutting off the fuel, and its seems to be about the same amount of running time when I first get it out before this starts happening.
Im totally stumped and having a hard time even looking at this thing anymore. Was hoping to finally be able to spend time with the family on the water, and enjoy the 1st free weekend off work in 6 months. Want to give up and just take it in and pay the price and have someone else look at it but everyone around here is backed up 3 weeks .
I just don't know what to do anymore. I normally in the past put close to 80 hrs on my boats a yr , so you know not being able to enjoy my boat time is totally killing me.
Please any help would be awesome and GREATLY APPRECIATED.
Thanks for the Help Shawn
