I have a 1988 4runner. I was having problems with the fuel pump and it turned out to be a bad ground wire. Fixed that, but while doing so we cut the fuel line by accident. This is the line coming from the fuel pump with the fittings on it. We wound up putting a rubber hose in its place and it seemed to fix the problem. A few days later it began to kind of hesitate while in second gear. I continued driving and this is what I am experiencing:

It starts up fine. I get and drive and take it to highway speeds for a while and it will die after idling for a bit. Then it wont start back up until you let it sit a while. The first time this happened my friend was pushing me out of the intersection and I popped the clutch in second gear and it started right up. The next night popping the clutch did not work so I let it sit for 5min and then got it to start, but I had to baby the throttle until I got enough rpm to get up and go. Acted like it was going to stall as I would give it throttle. then I would back off, let it idle again, and then ease into it. After I got the rpms up it ran highway speed all the way home. Did not experience the problem again driving through the neighborhood. I have started the truck several times since then, but dont trust it to drive to work. Any ideas?
