You need to pull your tanks out and completely flush. You can use tide soap to flush tanks. Replace all your fuel lines, filters, etc. I know you said you have new filters youll need new one's again. Also you should replace the fuel pump also just a stock mech. If you don't do all these things these problems will plague you for every. I know because I bought a boat that had sat for years with gas in it. The gas turns to cystals in your tanks.
