95 prostar 190 350 tbi.. when boat is warmed up and you shut off it won't restart sometimes. it's like it vapor locks.. i have changed cap, rotor, plugs , wires, coil, tstat, impellar, fuel filter moduel inside dustributor. when it won't restart it's not spraying fuel into the carb. so it's like something is telling it not to inject fuel.... any help would be appreciated.

Sounds very similar to the problems on my 94 ProStar 205 with a 350 TBI. Check the voltage on the green/white wire going into the fuel pump relay. It comes out of the ECM. You should have 12v on this wire when you turn the ignition to start. You can also check for power on the grey wire going into the fuel pump. Do you hear the fuel pump turn on for about 2 seconds when you turn the ignition to on? Here's a link to the thread for my problem. Indmar was VERY helpful when I emailed them. I explained the symptoms and troubleshooting steps in my thread. Hope it helps.
