Probably a plugged tank vent, and hence low starting fuel pressure. I don't remember if the cap is the vacuum release (will have a hole it it if it is) or if the vacuum release is in the charcoal purge system, but I'm sure it is plugged. Try loosening the cap before you start and see what happens, or better yet, leave it loose and drive a bit, then let is sit overnight and try. If the problem goes away, you need to get the vent fixed. Pressure in the tank will do the same thing, causing excessive fuel pressure due to restriction in the return line.

You may also have a leaking cold start valve or warm-up regulator. Get those checked if venting the tank doesn't help.
