2012 80hp 4 stroke wont rev out

[pstephens46]

At breaking point. I have now had to limp home 3 times now with the same problem. Run out to the reef is fine but at some point the boat starts running rough like a fuel problem and wont run much above 3000rpm. Come home had injectors cleaned twice, vst cleaned out, all filters, tanks and fuel lines replaced. Motor comes good after each time but then take it out and same problem. Already thrown $1500 hundred at this and had enough. Any thing i or the mechanics are missing?

All the previous cleaning made an improvement? Ran good for a period of time then failed again? Has the fuel tank been cleaned? Edit- you mentioned tank cleaning.
