My 455 did something similar, long story short it ended up being a loose ground on the fuel shutoff solenoid. Remove the left side panel and you will see it. My problem started as a coughing/sputtering problem, turned into a "won't start" problem before I found it.

The fuel solenoid pull-in coil is high current. Could be up to 5 amps. If you have a poor connection someplace along the current path, then the pull-in may not operate and thus, no start.
I agree with other posters. Corroded connectors, poor crimp or just a poor ground can become a problem.
Keep looking.

I believe OP found a bad fuel shut-off but you said something that might interest owners. A mechanic should have knowledge of testing proceedures and know what's wrong. Dealer that throw parts at it until fixed is a hack,not a mechanic. Owners can buy and install parts themselves much cheaper than paying $80-$100 per hour plus mark-up on parts. As you said "hopefully"he's right the first time.
