What is going on with this ETEC Please help.

[chugbug20X]

My boat has been in the shop for 18 days and counting. BRP sent out a new EMM got there this Thursday they put it in and took it for a water test. New problem the tec gets it to about 4500 rpms and it cuts out just like as if you turn off the key. They get it back to the shop and asked how the gauges were dropping out all at ounce or falling slow. They check for shorts none were found. Long story short BRP says its a lip pump. Do i need to fine a different tec. I love this motor but i'm scard now MN E225DHLSDF SN 05126673

Have they run the motor with a fuel pressure gauge installed to watch if the pressure drops just before the motor dies?

Did they check fuel output pressure from the lift pump at all speeds?

Did they use a vacuum gauge and a clear piece of fuel line at the lift pump inlet to evaluate the boat's fuel system for air bubbles in the line or a fuel restriction? That is all covered in the service manuals.

Is this a new motor on an older boat? Is the wiring used or new?
