That's real good advice. Wish I had taken it. So far, I've replaced a fuel filter that was perfectly good, a fuel pressure regulator that was also good, a fuel pump, likewise (that was fun), cleaned up the Air Flow sensor and replaced the fuel pump relay. And my Mr. Two just keeps running great for a while, then dies like the switch is turned off --- but it isn't.

It's the 3S-GTE engine, 1993 model. Sometimes it dies after a few minutes, sometimes I can go seven or eight miles. If I wait about 10 minutes it starts right up again! (Which is good, I can limp home that way.) Before I replaced the fuel pump relay I could hear the pump running right after it died for a few seconds, then it would stop. No error codes from the computer.

I'm stumped. Does anyone have any idea what's causing this? Or even some way to do some testing? Could the alternator do this, for example?

Any help will be GREATLY appreciated!!!!
