Ferrari Mailing List: Re: Hesitation troubleshooting resolution

[LarryT (l02turner]

A friend of mine had a similar problem with his truck - he had allowed the 
little round seal from a additives bottle to fall into the tank - it would 
float around and get sucked against the feed pipe to the engine.  The engine 
would stall and then restart!  He replaced all kinds of stuff - just like 
you did.

Those kinds of problems  happen once in a while and take forever to find...
