its probably the cold start injector along with the ignition module. mine is doing the same type of thing, but mine wouldnt start when the weather was under 50*. i changed the cold start switch, and it will start around 40-45 now. but i think its the ignition module, because its fine when its warm. the board is probably cracked and when it warms up, it expands and the contacts touch. try swapping the module for a new one
[edit] this happened after i put the new module in, it has only 500 miles on it, and they can die that quickly [edit]
