I'm on a road trip and my car keeps stalling. It hasn't stalled when it was actually moving. Only when I start it immediately stalls but it does turnover. Sometimes I can get it to idle for a while if I tap the accelerator. On my road trip I was consistently driving the car 120+ for probably over 8 hours. I was under the impression that speed would not kill this car. Could it be a clogged fuel filter? The problem seems intermittent. The car worked fine all day yesterday but then I drove her for a while today and then I'm having the same problem again. Anybody else had or having a similar problem. 01' BMW M3 Coupe.
