Just had major service done on my '98 GS 300 which has just over 100K miles and has been running great. Few days ago, as I was waiting at a light, the car did a quick sputter as if it was going to shut off. Panel lights came on briefly but car returned to normal. I got to work and when I opened the car, the dome light was very dim. When I tried to start the car, it wouldn't start. A second later, the dome light returned to normal and the car started fine right away.
Following day, I had just started accelerating from a red light and the car just shut itself off. Both engine and all electrical shut down. Luckily, I was able to cruise to the side of the road and put the car in neutral. A second later, car came back to life and started on the first attempt.
I took it straight to the dealer and they've had it for about 3 days and can't seem to find the problem. On board computer doesn't show anything and all electrical seem to test fine.
About 5 years ago, the car wouldn't start one night. Jump starting didn't help either. Next day, it just started on the first try. Took it to the dealer and they couldn't find anything wrong then either.
I really like my GS 300 but need to find the reason why the car would all of a sudden shutoff completely. Can anyone help me? It's still at the dealer and I'd like to give them ideas so I can get it addressed so I can keep the car.
Thanks!

Suddenly shutting down sounds like the fuel pump. Don't know if what you're seeing with the dome light and such is related to this situation or not. When you go to restart and it didn't start, did the car make clicking noise like dead battery or just turnover like normal and not start?

Yeah like Coco-bun stated that should be the first thing to check. Check the amps on the battery, And check all necessary wiring associated with the battery i.e. Terminals, Ground, Positive power cable etc.
I would agree with the guys guess above on the fuel pump.....But there is no reason you should lose all power unless you have a faulty battery or faulty alternator. Which leads me to believe you have an issue with the charging system. Most likely its something simple.
Again I would check all the basics first. I had a similar problem in my GS430 she was shutting off randomly. Problem was the power cable was loose and was also grounding out on the hood.

+1. If it's just a fuel pump, I think electrical should still be running off the battery. but since you said no panel lights, made me believe the battery was drained out.
I actually had a very similiar experience and I feel your pain. The culprit? A loose positive cable going to the battery post

Check your battery terminals if they are loose. The battery terminal connections that Lexus/Toyota used are prone to stretching out over time and becoming loose. They also aren't completely solid so the contact points are smaller than some other battery terminals. If the mechanic loosen the terminals and tighten them back down they could still be wobbly.
