[ST] Check engine - odd symptoms

[Shawn Mouser <srmouser@xxxxxxxxxxxxx>]

I'm hoping someone else might have had these symptoms on their bike and 
can impart some wisdom.

I have an '02 ST with about 20K miles. An odd set of symptoms occurs 
when the bike gets hot. At exactly the moment the fan kicks in the fuel 
gauge goes dead (drops to empty), the fuel light comes on, and the 
"check engine" light illuminates. This has only happened in stop and go 
traffic and doesn't seem to be an overheating issue... the bike never 
overheats, the fan kicks on, the temp gauge stabalizes, there's no 
change in how the bike runs, eventually I get moving again and when the 
bike cools back down to it's normal operating temp, the fan kicks back 
off and the fuel gauge goes back to normal. Of course the engine light 
stays on until I go through three cycles (without the fan kicking on 
and sending an error code) and then the brain resets itself.

I took the bike in once to my dealer since this started, but at the 
time I hadn't noticed all the symptoms... I just had an unexplained 
check engine light. The dealer basically reset it and said bring it 
back if it happens again (babbling some B.S. about how the battery 
might have gone weak/dead... which it hadn't). I'm hoping someone here 
has had a similar issue and might give me a heads up so I can point my 
ever so helpful dealership in the right direction.

Thanks,
