[QUOTE="Zimic, post: 435395, member: 20400"] Sorry for the delay, busy weekend. Replaced the ICM and the problem is not fixed. I have no other ideas, so it sits for now. EDIT to clarify: I installed the Howell FI. I have all manuals and guides. It ran good when I installed it and for about a year or so after. thinking it might have something to do with it I removed the FI replaced it with a Weber carb and replaced the fuel pump with a smaller one and a regulator ti ensure proper pressure to the carb and the problem continued, so after multiple test runs, I reinstalled the Howell FI. The problem: It runs great when you first start it idles smooth drives good everything. After 20-30 miles then the issue starts, it will start missing, sputter, if i stop it will hesitate sputter and even stall when i start moving again. the longer i drive it the worse it gets. Saturday i pushed it way to far and it stalled and wouldn't restart. luckily, I was by a buddy's house and only 2 miles from home, so he towed me back. I tried stating it about 2 hours later and it fired up. [/QUOTE]
