I was going about 80mph this morning in 5th gear. Suddenly, my accelerator went dead and became unresponsive and the car began to slow down. I managed to pull over to the shoulder and shift to neutral, when the car stalled as it approached 500 rpm and lower. I got it to start right away and the problem had disappeared and my accelerator worked once again.

I just had plugs/rotor/cap/wires done and they're all lexus oem parts. Other than this event, the car ran perfectly fine since the tune-up. Any idea of what could be going on? Can resetting the ECU and cleaning the throttle body help this problem is there a sensor that could have triggered the loss of the accelerator?

The linkage seemed fine and I do not think the throttle was stuck closed or open, because once I restarted the car, it was completely fine.

Car has 192,xxx miles and I'm running 93 octane.

Check and make sure there is nothing stuck in the air filter/intake pipe/throttle body opening. One time I sucked up a leaf somehow on the highway and it killed my car completely just as you mentioned. When I removed the airbox I found the obstructions

From doing a search, it seems that it could be my fuel pump ecu

yea might be the fuel pump system

so it could be:

1) obstructions in air passage (throttle body, intake)
2) may need a good 'seafoaming'
3) fuel pump ecu
4) fuel pump
5) fuel filter

missing any?

I know many of the questions I have been asking on the forums are questions that have been asked/answered before. However, the only reason I ask as I did above is to gather all the possible problems just to better equip my mechanic to handle it.

Maybe there should be a FAQ for the stalling issue; the information is def there, but the search function in this forum isn't necessarily the best.
