Honda Repair: 1992 prelude start/stall, honda prelude, hot afternoon

Question
I have a 1992 honda prelude Si4ws. This problem has been going on for quite some time. It started last summer, but then didn't seem to happen during the winter (not nearly as much atleast). After being driven for a while, 15 minutes or more and turned off for a short period of time. Like a 2 minute run into a gas station or something, upon trying to start it again, sometimes it will start, and then stall almost immediately (In this case, I watch the clock and wait almost exactly one minute, try it again, and it starts 95% of the time). Sometimes it will start and be fine. Only once has it failed to start after being parked all night, on a hot afternoon (90s and in direct sunlight) it wouldn't start at all. As a stab in the dark, I replaced the Ignition Control Module, it didn't fix it. I've read thru questions and have come up with the main relay as my answer. Any verification or other advice would be greatly appreciated. Thank you.

Chris:
Check your electrical connections to the battery and clean them up to make sure you have good contact. Check the air filter and replace if it has not been replaced for a while. Other thing to check is fuel pressure regulator to make sure it is working. Make sure before you replace parts that you are verifying the part is bad, if you think it's the main relay you can test it before replacing.
Good luck
