Roketa 150 won't stay running

[Jaybird09]

So my roommate bought a 2008 Roketa 150, I have owned a few and always seemed to have problems. Anyways. It wasn't running when he bought it. I checked a few things. (Spark, fuel carb etc) and found the carb was bone dry. The fuel pump wasn't allowing fuel to come to the carb. Soaked it in cleaner and fired right up. It ran most the day yesterday, but when we was on a cruise it just died and it won't start, when it does start it dies. I am dome with tinkering with it and he is not much of a mechanic at all. Any ideas on what could be causing this issue? Plug is brand new, gets spark, fuel is still running to the carb but battery need to be jump started every time. It's gotta over 5k miles on her as well. Thanks y'all.
