Well first I will start with this, when I bought the car It didn't run and that it was fuel related. They had an air Tec fuel pump put in 1 year ago and those things usually go in a year or less. So I swapped it with a good used fuel pump I had from my last build. Well Got the car running and it does fine when it's cold( besides the sputtering here and there on acceleration) . But as soon as it getting to operating temperature for about 20 mins it gets worse with the sputtering and even starts to back fire while driving. If you sit still it idles as smooth as even but as soon as you put it in the it will sputter backfire and eventually cut off. Now if I cut it off for a min and sit then it will make it another mile or so And start again. Really need some help on this one guys. Thanks

I would check your engine coolant temp sensor. If it is not reading properly the ecu won't lean out the fuel mixture as the engine warms up, and it will eventually get warm enough to not run. Is the car smoking from the tail pipe at all?

Yes it is white smoke, are you talking about the temp sensor right behind the top radiator hose
