Engine cutting out under load

Descant, fuel tank was replaced when I rebuilt the stringers and flooring. After we drained the gas this spring I looked into it with light and nothing unusual in regards to particles at the bottom of the tank. Fuel pickup tube was clear that goes into tank. It's also about 1/4" off the bottom. I can easily blow into the line that goes from the tank to the fuel filter and hear it bubble. I'll double checking the air vent line but it appears clear.

The fuel pump is mechanical and new this year. It's not the fuel pump.

The engine stutters then dies after it gets warm, and especially when rpm's get above 2,000. It can be running great for 5 minutes up on plane, then it losers power and quits if you don't back off the throttle. Even then it will quit if you don't shut it down and let it cool. It will restart but you usually have to let it cool for awhile to restart it. The more it runs, the longer you have to let it cool before it will restart. This all appears to be electrical to me, not fuel system.
