Take the ground cable off of the engine and look carefully at it. Many times it will loosen up, or corrode with rust at the head bolt connection. Remember that the positive side has to be in good condition, but so does the negative path back to the battery. The negative cable connection can look perfect by just glancing at it, but when you disassemble it you might be in for a surprise of a high resistance corrosion that is undetectable without removing the nut from the head bolt. When the connection gets hot from engine heat, and expands it will make higher resistance. You'd be surprised how many times people overlook the negative side of the system when hunting hot start problems.

There should also be a star washer to promote a good connection between the bolt and the cable, sometimes it gets discarded when the negative cable gets removed, and replaced.

Good information.
I will give it a try.
