When cold the engine starts and runs very well untill it reaches about 180 deg.F, up to this point I can turn the ignition off stopping the engine and then restart as often as I like. After reaching about 180 or operating temp. The engine may stop abruptly at any time, or if I turn the ignition off to stop the engine it will not restart. At this point I have determined there is no spark coming from the ignition coil bank to the spark plugs. After the engine cools off completely it will restart and run sweet as can be untill it reaches operating temp. And looses spark again or is turned off, at which point it will not restart because there will be no spark. I have replaced the ECM with a spare one I know to be good, but the result is still the same. I hope you can help. Thank you, Keith (bb650)
