How many miles do you have on your vehicle? Looks like the first two answers are talking about fuel pump / pressure issues, which is very likely. It is also possible that you have a failing ignition coil or sensor somewhere under the hood, crankshaft sensor possibly. Reason being is that you say when the vehicle is cold, it'll start fine, but when hot it acts up, until you let it cool off. Electrical components are very sensitive to temperature changes, and heat will generally reveal their malfunction.
Fuel pressure checking is a good idea, but typically a faulty fuel pump will happen regardless of engine temperature, not to say that it's not possible. Fuel pressure bleed down too, while a good idea to check, doesn't really seem to fit the profile. I would expect that if the fuel pressure is bleeding down too quickly, that you would also have a complain of extended cranking time in the morning, or after the vehicle has been sitting for several hours.
Some more information on the history of the vehicle, the vehicles mileage, and any recent (within the last 6 months) service or repair would help narrow down the possibilities.

I definitely support checking the ignition system - CMP/CKP possibly. Don't know which engine - the 3.0L 12V OHV or the 3.0L 24V DOHC.

Fuel pumps are not uncommon for a late 90's Taurus, and don't forget that in a system where fuel returns to the tank, fuel pumps can get warm too, causing them to not function correctly.

The bleed down suggestion is because many people forget to check that. You get 45psi, and then quit looking. More due dilligence than suspecting a faulty check valve is causing the problem.

Good added advice overall, however.

Make sure you have fuel pressure checked AND pressure bleed down.

A quick test for codes then a manual fuel pressure gauge would be my first course of action. Sometimes fuel pumps electronically fail intermittedly.
