Hi Everyone, I have a 45 series Troopie (84 model I think). It has been running very well recently. The other day I drove it 15km into town along a country road at around 80 Kmph. After about 10km it startes stalling at high speed. It was very sudden like power on to power off completely with no warning. After the speed reduced for about 10-15 seconds the engine would kick in again. Another few km down the road the cycle started again. Sometimes it would roll to a stop and I would wait a minuted and start her up again and off I would go. The distance between stalls gradually reduced until I was lucky to make it home. I'm trying to figure out what the problem is. I don't think it is a fuel problem because If I leave the accelerator in the same position while I'm coasting along when it kicks back in I was getting a back fire. This tells me fuel was still flowing while the spark was not. I don't think this could possibly be an air intake problem so that only leaves spark. I replaced the old breaker point distributors few years ago with an electronic job by and this came with a new coil. Anyone have any ideas how I could. Diagnose and fix this problem?
