Stalling Problem at higher temperatures

Hey guys first post here. I've read around a bit trying to see if this problem has been addressed but nothing seems to quite match it.

1997 Jeep Wranger, 4 cylinder, 5 speed manual trans, 92K miles

I'm at least the third owner, so I can't tell you everything that everyone has done to it. Here's what I've done:

Full brake system replacement (everything from the Master cylinder to the rotors and every line in-between)
Replaced Distributer rotor, cap, wires, and spark plugs
Replaced Air filter
Replaced Fuel Pump and Filter
Replaced Ignition Coil
Checked Fuses
Checked 02 Sensor

The problem I'm having is stalling at higher temperatures/longer running times. The first few months I had it I had no issues at all with stalling. She was behind on maintenance but running well. After a longer highway drive than I'd previously done (about 40 miles) I started losing engine power and RPM. The problem has worsened in the time since. For the last several weeks it will stall completely if I continue driving it. The stalling occurs in all gears, during acceleration, and while cruising. I work only a handful of minutes from the house, so I'm still driving her every day, but if I drive 10 miles or so consecutively it starts to lose power again. After she's sat and cooled for a while, she works fine again, leading me to believe it's an issue with operating at temperature rather than the distance. It doesn't overhead per the dash, it never goes above 215-220. I believe I have a bad oil pressure sensor as she will occasionally show the oil pressure bottom out and come back. It's not at all consistent with the stalling so I think it's two separate problems.
