I don't think cold water on a hot engine is a good idea. When the problem occurs, if it cranks good, but, won't start, have a helper crank it, while you visually check for spark at the plugs. You can carry a known good plug or spark tester in your glove box, it won't get hot. Then, take a plug wire loose, where applicable, stick tester in boot, ground tester to metal part of engine, engine cranking, watch for spark. If you have spark everywhere, use a gage and check fuel pressure. Any applicable trouble codes?

Maybe I should rephrase that.
The car will start, but it sputters and idles real low and eventually will die. If you leave sit for several hours it starts with no problem. Also, now the idle will run high.
I do we test things on the car.
Thank you

If you are fully obd1 compliant, 12 pin datalink connector, under lower edge of dash. Check for mil codes. Use jumper wire between A & B terminals at data link connector, key on, no crank. The mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes. Also, use a gage and check fuel pressure, some of the national brand autostores used to loan out a gage, if you don't have one. Without more information, all I can do is hunt and peck.
