I had one on a take-off roll when I was training in a Cessna 150. Got to 50KTS or so and was about to rotate when it all went really quiet. Had a nice long runway so plenty of time to get it stopped. I got towed back to the hangars and was later told that it was fuel contamination in the carb. I learned a valuable lesson that day because I did my pre-flight as usual and did a fuel drain. then I refueled and assumed that the fuel was good but there had been some water in the tanker. So take it from me, no matter what the situation or weather always do a fuel drain before starting that engine. I can't imagine that silence in the cockpit at say 800 ft and climbing or not as the case may be.
