I had an engine replaced in spring of 2018. Last season I only had 5 hours on new engine and it started every time. With boat out of storage and summarized I am having difficulty keeping it started. Once it shuts down I can not restart it just cranks. Its not been on long enough to overheat and the gauges look good. Prior to replacing engine I had fuel pump, alternator, and water pump replaced. The plugs and cables were replaced in 2016 but I have not taken boat out of marina all that much so there are not many hours on plugs and cables.

Could use a little more info like What engine is it? TBI or MPI? Do you have spark? how about fuel pressure? but any way start by looking at relays like fuel pump and so on the move on to connections at the distributor and coil, module and so on
