My boat has been stalling here and there this season mostly after it's warm. Last Sunday when we were on our way to our hangout spot, I lost all my rpms ( it didn't stall out though) while I was almost full throttle. I had to take it out of gear and put it back into gear and it ran fine the whole rest of the way there. On the way back, after about 10 mins of running it stalled out and would not start again. I always keep a tool set in my boat so I did my basic checks. Fuel pump was pushing fuel but there was no spark.(Thunderbolt ignition). After getting towed back and got the boat home it sat for 2 days before I got a chance to look at it more. Checked for 12v at coil. That was good. Check for 12v at white/red wire from ignition module. That was good too. Coil tested 1.1 ohm on primary, 10.5k on secondary. Hooked every thing back up and turned the key and it fired right up instantly like it always does. I'm suspecting a bad coil when hot, but is there any other thing I should be looking for? There's a big price difference between a coil and an ignition module. Sorry for the long post but I wanted to explain the situation the best I could. Thanks in advance for any responses.
