behind the bracket the boost control solenoid, and map sensor are bolted to.
It almost sounds like a wiring problem but then weird that it seems time / heat related.

Water temp sensor possibly?, as it gets hot it goes open circuit, fooling the ECU that its very very cold, hence goes very rich, and will flood a warm engine upon restart.
