04 4.6 explorer runs hot, not radiator hot, but low oil pressure light blinks twice before the SUV shuts down, what can this be?

SOURCE: Low Oil pressure light in idle at stop

Depending on the amount of miles, maintenance records, or how hard the car has been driven either by a previous owner, or by yourself. The engine's main crankshaft bearings or the connecting-rod bearings could be excessively worn.

Also, it could very well be a wiring problem to the sensor and/or computer causing the problem.

oil pump starting to fail

SOURCE: low oil pressure

usually that could mean a failing oil pump....or a clogged pickup in the oil pan, could also mean you have a leak somewhere. the car shutsoff because it protects itself from killn itself

SOURCE: 2004 Grand Cherokee: oil pressure fluctuates

if you know for certain that the sending unit is correct and the guage is accurate, then yiu may have big problems.....while the engine is running open the oil filler hole.. is everything wet with oil? or does it look dry or just a little lubed? you can allways install an aftermarket oil pressure guage(crappy tire) if you get the same results with that then you may have a week oil pump....worst case scenerio... need an engine rebuild as the moter may have wear issues.does the pressure slowly drop as the motor warms up? at idle ? does it jump up when you step on the gas?

The computer in your explorer, will not let your truck , because of a blown head gasket or bad seals you need to have it fixed or get a different truck.
