I have a 95 camry with 185K miles. I drove for 40 miles via highway, went to buy coffee, and when I tried to start my car again, it died within a few seconds. I tried to crank it again and again and the rpms would drop quickly. After waiting 15 minutes, it started and I gave it gas for 5 seconds and the car moved but drove very sluggishly. I brought it to the dealer and they replaced the IAC valve, air intake hose, engine temperature sensor and cleaned the throttle body.
After driving it for a week, the same thing occurred as above. The only difference is that after waiting 15 minutes, it started and drove smoothly. I brought it back to the dealer but they could not duplicate the problem.
Today, I drove home from work about 40 min via highway, changed clothes, went to start my car again and the problem above occurred. So, we took my wife’s car and came back 2 hours later. I started my car and it cranked fine. I let it run for 5 minutes and it never stalled.
It seems that the car only has problems when the engine is warm. If the engine is cold, it runs fine but when I park the car after driving it for a while, it wont start again until you let it rest for at least 15 minutes.
What’s wrong?
FYI, Two years ago, the dealer replaced ignition (Dist) cap, rotor, spark plugs, wires, timing and engine belts, and ignition coil. Since then, I have driven 40K miles.

Could be the fuel pressure regulator or vacuum valve controlling it is bad, this would allow vapor lock. The regulator is located at the end of the fuel rail, a small can.
Follow the vacuum hose from the can to the control valve that is an electric power solenoid.
When hot starting the engine the vacuum hose going to the regulator should be drawing vacuum for 90 seconds.

sounds like a fuel problem.

Could also be an exhaust issue. After running for a while, if the flow of the exhaust is screwed up lets say in the cat converter (like me) then the backpressure is screwed up and the exhaust not flowing properly can perhaps be "choking" your engine. I'm havin the same issue but I know what mine is: my father-in-law stuck a piece of pipe into the cat to seal a hole, which is screwing up back pressure.
Now I gotta tear it apart for the 4th time!!
Hope I was any help. If all else fails, check into that.
