[QUOTE=ShefmonC3;1594351247]When you say "won't start after driving for awhile" do you mean it will not crank? Cranks slow or just cranks fine but won't fire?[/QUOTE
She wont Crank, turn over at all, all connections are good, new battery, after 30 min, she starts right up

OK, I was going to suggest that you could have bad battery (bad cell) and low cranking power but you bought a new batter too. I know you said all connections are good but I would check the battery to frame ground (at the frame) one more time for a good, clean connection. There is a fix for this... just need to track it down.

I would be looking at wring or when this happens hook up a remote start switch directly to the starter and see if it cranks over.

put jumper cables on your battery from another car and see if it starts ( at the 30 minute hot engine point where it won't start by itself).
if it starts then the connections are good since you will have just shown that the connections will pass the amps the hot engine requires.
a hot starter and engine requires more amps than cold and sometimes the battery cannot supply the amps.
the solution is to buy a bigger battery , the biggest highest cranking amp battery you can find. or buy a high torque starter that does not take as many amps.
sometimes the starter solenoid can't pass the amps, but that would be a cold and hot issue both. but if you add amps to the system via jumper cables and it starts then you have an amperage supply issue and not a connection issue.

I would suggest running at home. When it fails take a meter reading from frame ground to starter lead from battery. If you are getting voltage and starter isn't moving then switch to current. You need a meter that has a high current scale (30 or 60Amp) And see if it is drawing any current? Would prove the positive battery cable from battery to starter. Then as someone suggested pretty good chnace you need a starter. Othe r thing you could try to use a battery pack and go on frame ground and jump positive right at solenoid.

I just walked in the door from rebuilding the HEI. It did have a bad pick up coil. I dropped it back in and it fired right up. I set the timing and gave it a test drive. I'll go back outside in 30 minutes to see if the starter acts up again but it really doesn't matter as I have one of the new fangled starters from DB Electric order.
Thanks again everyone.
