Today I went on a drive in the mountains with 4 other Ferraris and several other cars. The drive went well (aside from the fact that the car handled the roads better than the driver!) with one noticeable exception. On two occasions we stopped to take a break. When trying to start the car after the breaks, it refused to crank. With the help of the other guys pushing the car I got it bump-started both times. Later, when we stopped for lunch (which took nearly an hour), the same problem recurred. It happened one more time, when I stopped at a food store shortly before arriving home. This time I had anticipated trouble and parked the car so I could push it myself on a slight downslope in the lot; sure enough, it would not start and I managed to bump-start it myself. (And I should point out that today was one of the hottest days here thus far this year.) When I put the car in the garage I opened the engine cover and let it cool off. Less than 2 hours later I took the car out to dinner and this time it started fine, both going and coming. It has generally never given trouble when first starting out or after short drives. It seems obvious to me that this has something to do with the heat the engine retains. I've noticed when I park the car and open the engine cover, there is an incredible amount of heat coming off the engine, and it takes quite some time to dissipate. But the water temperature gauge always reads quite reasonably and I was led to believe that 328 engines normally run quite warmly. Is this in fact so? I should point out that the battery is quite healthy and does not seem to be at fault at all. Does anyone have an inkling as to what's going on here?
