What causes an engine to over heat and loss of power is, bad timing, bad radiator, bad thermostat, bad water pump, clogged catalic convertors, fan clutches/ electric fans, hope this helps in a way.

If your car idles and runs smooth after everything you've done, I would almost say clogged catalytic converter just by the power loss.

if you are sure there is no spark and you have replaced the coil,then the only other thing it could be is your spark control moduel.it works off your computer to tell your plugs when to fire..somettimes they go out only when they heat up and will start working again after they cool down,,but sometime they don"t give you any warning and just stop working all together.. would say you have a bad Spark Control Moduel.....it is pretty easy to fix, just make sure you use or buy the right tools to take it off , ask at the Auto parts store to get the right tool, and the right part..

You could try another oil pressure sensor or test the oil pressure with a gauge at the sensor port. If you think about it, the truck goes into a failsafe mode when there is a problem. You could go into failsafe with high temperatures too. The water temp sensor could be bad but with the oil light coming on, the oil sensor should be your first choice.

You can get a free scan at Autozone or Oreillys and it may show the problem. Sometimes it takes a better scan with dealership type diagnostics because the self-diagnostics on your truck is limited.

Failsafe mode would cause the power loss because the truck is designed to kill cylinders and to use the dead cylinders as hot exhaust pumps to cool the block.

SEEMS LIKE CAR IS SLUGGISH AND LOOSING POWER WHEN TEMP IS HOT.


id maybe try going back to 87 octane gas cause 93 may make it run better but it will run hotter too and that can cause premature detonation and spark knock
