"Well I had a marina Change In

"Well I had a marina Change Injectors 3 and 4 and also the tps sensor , called me up and said it was ready , used it last night , it seemed fine , snappy again had power ./ then after a long idle watching fireworks started heading back to Dock and No POWER and then today I tested it again, . when it is in nuetral sounds Great, revs RPM's right up . then click it into gear , I have vibration and only goes up to 3000 RPM when I Floor it .. if I play with the throttle up and down it will go up to 4000 RPM,s , I have to Bring it back to a Marina again!! I am stumped .
FUEL PUMP ?????? .. I am starting to Miss my old Honda which was 11 years older, any Ideas or any simular problems Out there , I have Drained Fuel , changed all filters , plugs , had diagnostic check.. I have no Confidence in my motor now ....I expect an Injector again , but what is causing this .."
