The Dealer did run a diagnostic and a few other tests on fuel pressure. The engine light (red and yellow lights) came on and an audible beep sounded each time it occurs. They made a few calls to Chaparral and at this point everyone is guessing. I am going to start with the basics and work my way back from there. Thanks for the advice and suggestions. I was hoping this had happened to someone else on this forum and it would be an easy fix. I will keep you updated as I go and hopefully find the solution before it gets too cold and I have to winterize the boat.
