1998 Nissan Frontier, when I disconnect my negative side of the battery, my engine will run fine; however when I go over about 2000 RPM's it cuts off. I had my alternator checked yesterday and it was working even when a load was applied.

Never disconnect a cable while engine is in operation, you're asking for trouble.

Best scenario here, have the charging system tested for no load and load. You sounded like the regulator is not controlling the alty.

Also do an open voltage check on the battery. A good battery will read 12.4volts or better before starting. While running when loaded should read 13.2-14.5 and shall not exceed 16volts. Anything over 16v is overcharging killing the battery and also the regulator is not up to par.
