My 12 valve would run for a few minutes then shut back off. I suspected the lift pump, and sure enough, the spring inside was broken, so the plunger wasn't contacting the cam anymore. I replaced it, and it runs perfectly. Not necessarily the cause of your problem, but it's worth a look. It could also be your overflow valve.
Gotcha what bout sometimes when I let it sit and idle for a lil while it will start to white smoke and act like its getting to much fuel till I clean it out then no white smoke
Mine just had same problem white smoking for me was due to feezing temps. But mine would not really run just for like 30 sec then die. I changed the return hose which had cracks in the end not sure if that was the problem. And also my prefilter o ring was shot so maybe sucking in air there and changed fuel filter no problems at all after 300 miles.
