Lexus: Starting problem- GS 300

I am wondering if any NG reader has had this problem:

I have a '98 GS300. The starting problem appeared about 6 weeks ago and it
has been intermittent. When I turn the key to start, there is nothing- no
lights on the dash, no sound - DEAD. I immediately try it again and, no
problem- it starts! The problem was occurring daily, weeks ago, and did not
reappear until this morning. In one instance only, the car started on the
first attempt but was making an unusual grinding type noise. I shut the
engine off and there was engine overrun for a few seconds or better put- the
grinding noise was slowing to a stop although the engine was off. Again,
this happened just once and MAY be unrelated to the problem.
Lexus dealer service told me that they would unable to diagnose the problem
unless it occurred for them.

Anyone had this??

Thanks,
Stu
