It turns over and occasionally fire but won't stay running

You need to start by doing a compression test, first pull all the spark plugs out and crank the engine over make sure no water is in the cylinders. Connect a compression gauge to each cylinder 1 by 1. Verify your readings are within 10% of each other.
