Default Yamaha hpdi experts please help

I have a 300 hpdi. About 2 months ago I was out. Ran great. Get into some shallow water so I trimmed it up, and it stalled. Put it back down, and started back up. Went out about a month ago, and again stalled when trimmed it up. This time couldn't get it to restart. Had to get toward in.Going to try to see if I can find the issue tomorrow afternoon. Was hoping one of the hpdi gurus could give some insight to where and what I should look for. Thanks

Loose wiring on the motor? kinking the fuel line maybe? It could be a non Hpdi specific problem

I had a similar problem a few years back with my 200 hpdis. Boat ran fine but when I would trim up while on plane the boat would lose power, almost like it would shut off. I finally isolated it to the starboard motor by playing with the individual trim while running. It turned out the main battery/power cable from the engine to the batteries had cracked from 7 years of bending and kinking when the engines went up and down. I ended up changing both out at a cost (i just pulled my invoice from 2007) of $358.97 each for parts alone. This did not include labor.

I'm thinking it is fuel related. It turns over fine. Just sounds like no fuel. Is it possible a stuck float in the vst from being trimmed? Primer ball stayed firm. Never lost prime.

The "real" expert, Jethro, has left the building.
