either your battery does not have adequate cranking amps or your starter motor needs overhauling if new battery, i would pull starter and replace
Remove starter and bring to an auto parts stoe that is equipped to check it for drag and amperage draw Check battery cables for looseness and/or corrosion Load test battery
sounds like your fuel pump is gettin hot
Once it cools off it will start.
could be that the coil is getting hot and wont restart until it cools down.
Your problem may be due to a bad starter, not an alternator. An old, worn, or damaged starter will give the impression that there is not enough power to turn over the engine or give no responce at all as if the battery is dead. Then after it cools down it may be more willing to start. Give the starter a good tap with a tire iron while someone else turns the key when it won't start. Try your best to be syncronised with the ignition and tapping the starter. If it starts right up you got a bad starter. It may seem like a tap will get you by but it won't work for long.
Most likely the starter should be replaced. When it heats up, it will turn the engine with a lot of strain. like the battery is low. When it cools down, it will turn freely.
I had the same problem on my 1988 and would have to leave it on. On that motor, there is a heat shield that surrounds the starter and if it is not there, when the motor heats up it will transfer that heat to the starter simulating a bad battery/starter problem. Once it cools down it starts fine. Start looking from there or get a remote starter (like I did) so you can leave it running when you run into somewhere fast.

it is 1991 chevolet caprice....ecm
When this was happening on my 1999 3.8 Liter Intrigue, I suspected the starter switch, but when I took it in to have it looked at, all it was, was a worn out Battery. They replaced the Battery and the problem went away.
Yep. When the wire is cold, the current flows from the battery to the starter very easily. As things get hot, the resistance in the wire becomes so great, and the current needed to crank the engine is so high, it just cannot push enough current to the starter until the wire cools down again. That's the cause. I suggest you go explain it to someone at Pep Boys for the cure, because other than replacing the wire to the starter I have no cure for you. Maybe that IS the cure. Phil
It may restart when it cools down or you have toasted your engine. Where is your common sence. Stop next time that happens.
Check the positive battery cable to starter connection. This was the source of lots of problems. As you have to work near the exhaust, wait until the car cools. Disconnect the battery cables, as otherwise it will be an electrical disaster if you hit any metal with the wrench while tightening this connection. It took a 15 mm wrench, putting the car up on blocks, and some arm contortion to get it tightened.
