So I started by TJ last night and it started perfectly but then immediately dies like it wasn't getting any fuel. Tried to start it about 5 more times and same thing. Had it towed to the mechanic today and he started it up no problem. Any suggestions on what it could be? About a month ago, for a span of a couple days, when I would first start driving it would act like it only had 50% power when I would apply the gas. After a couple minutes of driving it would run normally. There have also been times when I disconnect the negative battery terminal to work on something, the first time starting it there would be a lag to the power for a couple seconds and then it would run normal. Any thoughts and suggestions are greatly appreciated. Cheers
