It could be several things. It might be the fuel filter, the fuel pump, timing may have changed, spark(ign or weak battery). If it is a points type distributor, check point gap. Loose wires in cap, corroded cap/rotor. Carb may have dirt in it, floats off etc. Another long shot could be a bad starter. It might have a bad spot in the armature which would cause it to not turn over or have to hit the key more than one time. Check your electrical connections at the starter and battery, they maybe corroded or loose. Just a few ideas.

What you are referring to is heat soak on the starter. This normally only occurs after you have been running or driving the car for awhile. The car will not start or turn over slower than usual due to the heat that has been absorbed in the starter. After the engine cools down, usually they will start. As for putting on a remote (F-rd) starter relay, yes this is something you should be able to do yourself at home. You can also buy heat shields that attach to the starter and deflect some of the heat. I have used these in the past with no problems.

Summit has several different companies heat shields on ther website. The most expensive one is $26. I even have one laying on my shelf that i'm not using.
