If the issue persists it might be worth while to check the grounding, which can be intermittent if a cable is corroded or not firmly bolted on the block/frame. A couple of 4-6ga cables will get the job done if the issue is intermittent and you'd like a low investment trial+error fix. I had a similar issue a while back, but it was affecting the air and fuel flow, so causing stalls while running etc.
