I installed a new fuel pump , water seperator and new coil and still stalls a few seconds after planening sometimes it will start immediately and run again for a minute or two and then stalls again but sometimes it won't start anymore until engine cools down and it will start again , idle is okay and starts very easy . I'm getting frustrated but I can't stop now because I have already put in too much money in this boat for it's value I got the boat cheap but I had the interior strip and redone , a new full top canvas , brought it to a boat shop to make it running , had the 888 outdrive tuned last fall and test run it in the lake with the boat mechanic that time everything looks to be fine before storing it this past winter and I was so excited launching it this summer and got a slip at the marina but then this stalling thing is always happening and it's just really very frustrating for me and money is tight and exceeded my budget . Today I'm going to change the fuel host from the main fuel tank going to the seperator but I don't think this will solve the problem a mechanic told me that sometimes when a fuel host is so old the diameter of the hole get's smaller when it get's hot and from the build of particles on the linening of the interior I don't know but right now any advice I will take it , thank you for reading .

Have you solved the problem yet?

Try hooking up a outboard tank to the pump to bypass the main tank. If the stall goes away. Main hose plugged.

I agree, try using a 5-gallon gas can to bypass the main tank. The main tank could have a lot of sediment in it that gets stirred up when the boat begins to move/get bumped around.
