Hey everyone thank you in advance for any tips! I have a 69 grande matching numbers with a 302. I've gone right through it...new starting/charging system.....new ignition system...new fuel system...everything...brand new. It runs like a top! However, I had it out 4 times, and it left me stranded to be towed...4 times.
It runs fine for about twenty minutes to 1/2 hr...then it dies, just like it ran out of gas. When I try to start it up, it won't crank but once...almost like something is...

‘69 grande won’t run when hot
