OK folks, I replaced the plug wires as the thing was missing all the time. The hesitation and sputtering stopped. Took it out in the evening after changing the wires and it ran like a new car for 2 days. Yesterday, it got up a little over 90 degrees here and, it was running good, and then just started sputtering and dying. Wait 5 minutes, start it up and drive it a couple miles further and dies again. Finally gave up, waited until last night after it got down under about 65 degrees, starts and runs like a new car again, no problems at all. Talked to a mechanic at autozone this evening and he was pointing at the fuel pump. I can't see or hear any vacuum leaks. It has always seemed to me that the problem with it dying and then not starting occured when there was less than a half tank of gas, but ???? Glad it runs great when it's cold out, but summer's coming fast.

Better to ask a question and be THOUGHT a fool for 5 minutes than to never ask and BE a fool for life.
