Has it overheated lately?
My wife overheated our Galant and it just stopped working, it cranks but that's it.
I pulled the sparkplugs and found them wrapped in a gewey jelly like substance. Like an oil/antifreeze combo.
I am going to replace the entire motor for $1000 as taking it to the mechanics to theorize and practice may cost more.

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

Diagnosis must begin with scanning your Engine Control Module to find out why it has turned the light on. The car may seem to be running OK, but there is probably a problem that is causing you to use excessive fuel and/or is threatening to destroy some high dollar parts like your catalytic converter.

The first thought that comes to mind is a high pressure oil leak. The
injectors have a snap ring on top that sometimes becomes detached and
it will create these symptoms.
When you depress the brake it sends a signal to the PCM (Powertrain Control Module) and the PCM increases the idle because it predicts you are about to shift into gear. If the truck has a high pressure leak inside the engine it will have a hard time building pressure initially and once the oil warms and thins out the High Pressure Oil Pump cannot hold the pressure and the oil leaks faster because it is thinner.
You may have a leak around the pump area which is under the turbo also. The IPR which is the regulator that controls the oil pressure may also be bad. It is directly under the turbo as well. The IPR is located under the turbo on the High Pressure Oil Pump cover. You stated the seals were leaking on the IPR itself? If the orings are damaged or if the screen in the end of it is collapsed or even punched through with a small hole it will need replaced. Screen damage is usually a sign of debris entering it from either dirt from a previous repair or something is coming apart inside.
Make certain you have clean oil and fuel filters. Yor may want to check fuel pressure as well. It should be somewhere around 55psi on acceleration.
Additionally, I suggest check for voltage at the connector on the fuel pump. The pump is mounted in the filter housing on the frame and the connector is at the front of it. The pink and black wire should have 12 volts with the key on for about 30 seconds. If the pump has voltage but is not running, then your pump has failed. If there is no voltage then check fuse 2.40 in the central junction box. This is the fuse that feeds the inertia switch through the fuel pump relay. I have included a fuse box layout and a wiring diagram (click over images for zoom)...
Additionally, will need to scanned the PCM to know if some fault code is stored there.
Keep us updated.
