96 Montero Lost power and died.

My montero was running normal, then within 5 min, I began to loose power, the dash lights dimmed and eventually went out, the radio went out, and the engine started seriously stalling. There were also very loud "clanging" noises. The engine was extremely HOT. (All fluids were fine, I put a new alternator in Oct 06, a new sillanoid in Jan 07, and a new transmission and spark plugs within the past 5 years.) When the engine finally died, I tried to re-crank, and all I got was a clicking noise. I went back today, jumped the battery, and drove it home, but there was still no lights on the dash, and the engine began to heat up once I almost made it home and the engine died again. There were still rattling noises under the hood. All this also caused the battery to loose it's charge. Any suggestions? Could it be a fuel filter, or something with intake?

Any help is greatly appreciated.
