Yes, we aren't the only ones. Do a search for throttle cutting out. The ecu reflash has worked for some but not for me. The cut out doesn't produce a code or turn on a cel so the dealer is dumbfounded. Luckily, I can read and other people have had the problem as well so I printed out some snippets from the forum, took them to the dealer and told them to order a new relay switch. I need to call and see what the deal is but I have a good feeling that will be the fix. There is a thread somewhere that has the service bulletin from Lotus regarding the problem. I would suggest having this on hand when you go to the dealer. If I had to hear "we can't fix it until we can duplicate it" one more time I was going to lose it. I found the bulletin:
SERVICE Date: 03.08.06 2006/20
BULLETIN Model: '06 Elise/Exige a.c.
Service Manager Service Reception Supervisor Parts Manager
Lotus Cars Limited, Norwich, Norfolk, NR14 8EZ. England.
CLASS 3
TITLE: Momentary engine power interruption.
REASON: It has been found that on a very small number of '06 model year cars, with an unfavourable tolerance
a.c. control module, it is possible under some circumstances that sparking across the a.c.
compressor relay contacts can cause a voltage spike which results in the engine ECU resetting.
This will be experienced as a momentary interruption of engine power, and is likely to occur only
very occasionally. It is also possible that a throttle related trouble code may be set. e.g. P0638.
Action: If this symptom should be reported, it is recommended to replace the a.c./fan control module

Good luck. Let me know if they get it fixed for you. Seems like in the other threads no one came back to post after the problem was fixed. lol
