Have a 1992 Force 150 w 211 hours running time. Three times last year and first time out this year, while cruising at mderate speed and engine running smoothly - it quites, no sputtering more like shut off. It will not start immediately, but if I wait 3-4 minutes then hit the starter it fires right off and runs fine. Any suggestions.<br /><br />I'm considering replacing both of the ignition "black boxes" but the $200.00 each cost is stiff for a guess.
