EFI cars with recirculating fuel systems don't get vapor lock.
Does it have spark when it won't start?

Any codes when it won't start?
Have you checked the fuel pressure when it won't start?

Is It The Fuel Pump or Something Else? - Third Generation F-Body Message Boards
these 2 threads are dealing with the same issue on the TPI board. sounds like the exact same issue to me.

Doesn't sound even remotely like the first link.
You've checked spark and fuel pressure when it's not starting?

Last week, I was on my way to fix an AC at a friend's home, when it stalled out.
After a couple years of dealing with this, I pulled out my freon tank and gauges and shot some freon at the base of the distributor, where the ignition module is.
Cooled it right down!
When I cranked it, it coughed a few times then fired right up, and I went straight to get a new module.
It's only been a week, but it's hot as hell here in Vegas, and no problems yet.
