Power cut at high rpm

Just wanted to know if anyone else has this problem. My 94 E420 cuts out its power several times while the rmp climbs to 4 5 or 6 thousand. It feels like the car is hesatating to keep going faster.

Thanks in advance,
Charles Morcos

If the power is actually cut, it sounds like an ignition problem. Plugs, wires, and caps, are the usual suspects. If the power is simply lacking at any RPM above, say 3000, then your cat may have collapsed internally. You may want to post this in the 124 section in case there are any 124 specific reasons for this problem.
