Question about Ford F-150
Your computer controls top speed and rpm's so you don't go past rated rpm range and blow the engine. It's a good thing, as I've thrown rods out the side of blocks, and broken cranks, due to serious over-revving. Could also be a fuel starvation issue, if it's associated with a complete power loss at various high rpm's, (power comes back after you let off it for a second or two). But, what you're describing sounds like the ignition limiter cutting spark every other firing, which happens at the same approximate rpm, (6500-7000), to control rpm limit.
