Engine cranks then stops

I have a 36 Dodge sedan with a 350 Chevy engine. It has a 2 barrel carb and a Chevy HEI distributor. The problem I'm now having is it cranks over for about 15 seconds then shuts off. If I immediately try again it won't turn over. If I wait about 10 minutes it does the same thing again. It just started to do this. Before I could crank it until the battery went dead. I did put a jumpit on the battery even though the battery was still turning it over good and it didn't change anything. It has a 350TH trans but it don't have the neutral safety switch hooked up yet. It seems almost like something kicks out on a thermal switch but I haven't seen one. Any ideas?

I concur with a starter issue. Sounds like your armature is locking up in the front or rear bushings. Tear the starter down, check the bushings, brushes, etc. CLean it up and lube it up if nothing appears to be broke or worn out. Wheel grease works fine in the bushings.
Good luck.

I would say it is time for a new starter. Although I have seen new starters do this at times. I suggest putting an early ford style solenoid (fender mount) in series with your delco. I also recommend putting a starter button on it. On high compression engines, I leave the ignition off until I get the engine spinning with the button, then hit the ignition.
Other side of the coin.... If you need to spin it more than 15 seconds to start, you have other issues. Your starter is probably protecting itself,(like you said) on thermal overload. 10 second spins MAX. Speed

Thanks everyone. I had a feeling it was the starter. I'll check it. I'm new to hotrods. I built and raced Harleys and Vmaxes for 40 years and just started on working on Hotrods.

I use to build & run Harleys myself.I started out on hot rods then got into Harleys big time.I
Went 3 yrs without a 4 wheel vehicle.The closest thing I had to a car wuz an Old 45 w/ a sidecar.LOL.My quickest ride wuz a 76 Sportster that started out as a bar hopper.$6000 later it did a best time of mid 12's.On my 5th run,the drive chain snapped & the front sprocket rolled the chain up into lower case & busted it into a buncha tiny pieces.Talk about sick.Rite after that,the kids started comin & that wuz the end of that.They r grown now & my interest has been renewed !!!

You're reading my mind. Cables and connections are the first things I think of when someone says hard starting. You can never have too many grounds either.

First thing I did was check connections, everything good. My first street-strip bike was a 66 XLCH with a bolt on hardtail flat tracker frame, Dytch cylinders and 4 3/4" stroker motor. Would run hi 11s. My last one was a 2003 Vrod with a turbo. It had 172.5 rwhp. and was featured in American Iron Magazine. It would run hi 9s. I had a quintuple bypass 5 years ago and that ended my bike racing days. Now I'm enjoying hotrods. I also have a 57 Chevy post car I'm rebuilding. It has the original 283 that I want to a mild build. It had been stored in a heated garage since 72.

Hi guys, just wanted to follow up. I found the trouble. It turned out to be a bad positive wire at the crimped on connecter on the starter post. It had a lot of corrosion on the inside but not real noticeable on the outside. I cut the wire back about an inch to make sure I had good wire and used a solder-on connecter. Now everything is good. Thank you for all your suggestions. Bill
