Water temperature and stalling out

[DanEC]

Those sort of sound like the classic signs of a dying coil. They will fire your engine OK when cool but as they heat up over an interval of time and the voltabe output starts falling off. Once they cool off they will fire the engine up again until they heat up and then they shut down. But, could be several other things too.

Your water temp. could be a little high for your engine but I agree with Dan that this sounds more like a coil or some other issue related to ignition. My engines, which are racing engines, run at around 220/230 degrees F which is where they make the most power.

When it stalls and you try to start it, does the engine turn over easy? Also do you notice any roughness in it's running just before it stalls? Will it do this if you just start it and let it set and run for a little bit?

The engine is also a racing engine built by Coast high performance When it stalls the engine will not turn over. All that I get is a single clicking sound. I have not noticed any rough running before it stalls.
Typically I start it let it run at idle until the oil temp and water temp gauges start to move.

Thanks for your reply.
