I have a 1999 Larson cabrio 330 twin 5.7 gs engines
After driving it for about 45 min. it dies and wont restart for about 50 min.
when I bought the boat 4 months ago the dealer put in new fuel pump and carbs
The boat still took to long to fire so the mechanic change the coil, before this the boat started hard but ran great.
Since then I have change fuel filter, distributor cap and rotor
Ran it off of the other gas tank. and that motor has no issues and it still does it.
Last night I swapped fuel pumps from one motor to the other and still the same issue did a pressure check on it and it was 8 pounds.
So here is what happened last night late, After running 45 min. the motor died I pulled the coil wire and sparked it off the motor to check for spark two or three times put it back on and motor fired up perfectly. I shut it off 2 min later and it wouldn't start so I repeated the coil spark thing and it started right up.
The weird thing is that after the motor dies my electronic (depth finder and GPS) go kind of goofy.
Any help or ideas would be greatly appreciated this has me completely stunned
