Maybe someone could give me some clues why the motor will start intermmitantly but when i give it the throttle it dies and i only move the level barley , i unpluged the relays in the box and moved the wires around in the box and i got spark , question is are the relays the ing and fuel relays standard chev or mercruiser only and can they cause a problem like im having

If it has one, make sure the shift plate isn't doing something it shouldn't.
The barley moving the throttle may be your issue. You do know that when you shift in gear the motor cut off for a split second because of the shift plate so it can shift into and out of gear?

no shift plate or interupter on the bravo three, but can you tell me if the relays in the box the one for the system relay and the fuel pump are the same , they can plug in to both spots , i cant find it in the manuel but the serrira web site list them as the same

sounds like ign module taking a crap...

The realys are the same and they can go bad. I would disconnect the throttle cable and control the throttle body by hand to see if it still looses spark. If it runs fine then you need to look for switches on the shifter, or maybe cable stressing system wires making intermitant connection. If it looses spark, then it sounds like ignition module or any number of other things, but I think I read that you change it already. Please confirm what all you have done.
