Outboard starts and idles. The when full throttle applied, goes to full power and then boggs down within seconds. Almost like a switch goes off. Seems electronic..... Fuel delivery is good.

Ok do you have a timing light? We need to check spark when engine is acting up. Connect the timing light to each spark plug wire watch the flash of the light it should be steady with no dead spots on all cylinders. Post back with engine serial number and the findings of your test.
