Yes, my 2003 did the same with about 75k miles on it, stranded me on days it stayed under 40F unless I plugged in the block heater the night before, then it started like a champ. Dealer replaced the relay and a control unit under ESP warranty. There's no way to fix this one without throwing parts at it.
SOURCE: truck will not start
check to make sure you are getting fuel, when an electric pump heats up they quit working,then when they cool down they might start workig again until it heats up again. or if you have a performance chip in your pcm they short out pull out chip and see if problem is still there
SOURCE: 2001 ford taurus wont start
It could be bad plugs, plug wires, a bad ground will do this as well. Check to see if it has the three main things.
Spark
Air
Fuel
Anther common problem is the crank shaft speed sensor. It will cause it to not spark and not start.

could be the solenoid on the starter is going bad. but best bet is to get a whole new stasrter as a new solenoid comes on it. solenoid is almost as expensive as getting both together

It sounds like a common problem with the fuel pump relay. I am surprised your mechanics didnt think of this first instead of selling your lots of other stuff...or maybe I am not surprised!
The original part is a burnt orange colored RZ-0067 Main Relay and is found underneath the steering column. The relay's dimensions are close to the top flap of a hard pack of cigarettes. The relay is secured by a 10mm bolt, and is easily accessed by removing the front panel above your shins.
The said relay is frequently cited as the chief cause of not being able to start the car on a hot day. See http://www.honda-acura.net/forums/archive/index.php/t-85539.html, http://honda-tech.com/zerothread?id=1319817&postid=16772789 and http://autorepair.about.com/cs/troubleshooting/l/aa010301a.htm. It is also the least expensive (e.g. $35-50 for part) that a novice can do at home!
The RZ-0067 relay appears to have been replaced by the RZ-0063. See http://g2ic.com/forums/showthread.php?t=27612. It is identical to the RZ-0067 except it is black. See http://63.150.115.104/CommerceGateway/picturesHonda%20J-Pegs%5C39400SH3003.jpg
This is a very common reoccuring problem on Acura Integras as well as other Honda vehicles.
