my 740 died on me three times while driving in the last two weeks. I went thru the faqs to see what electrical I hadn't replaced. Tonight I took off the old power controller and noticed the screws were loose (first clue in faq) so I put the new one on and will see in the next couple of days if it dies. I now have replaced every electrical part under the hood. Tomorrow I will go down and buy another 4 rubber bushings for the ac and alt. I have the motor mounts and the tranny mount coming in the next week. I should be down to little vibrations after that. Thanks all
