Last cpl times I have went out to start it it rolls over like 5 or 6 times. It has 2000 miles on it all stock. Last night while I was driving I stopped to watch some deer and lights flickered once. While I was sitting there I wanted to see where clutch engaged so I rev’d up slowly and when I let off it stalled. When I left that spot at idle was 11.7volts. It took bought 100-200 feet to pick up to 12.7 v and that’s where it ran. So my question is it fuel pump or regulator? Can’t see it being fuel since the lights flickered when I was sitting at a idle. Just looking for a lil input
