2000 GTI Seadoo - Idles on it own - Accelerates (out of water using flush hose) fine

[PakEnter]

But when I put it in the water and get into open water and squeeze the accelerator (trying to get up to full speed) the boat accelerates up and then promptly quits. Restarting it and then squeeze the accelerator again and getting the same result. I didn't want to take it into a shop if it was something that I could fix. Replaced the plugs and got the same result. Take it back out of the water and we are back to idles fine and accelerates fine (out of the water only). I have heard of limp mode but didn't know if this is what has happened and if I have to take it in to get it out of Limp mode. Any suggestions?

Old gas? new gas? Any recent maintenance performed? When is the last time it ran well?
