Battery may be on way out
first of all if you have a good battery and im not saying you do but it could be fuel or air intake, your starter, or loss of compression.. but to test a battery you have to check it before you start your car then get someone to crank it and test it again because all battery will keep a surface charge but they loose that once a load is applied

Connect the positive cable to the positive battery post on the donor car and on the Corvette. Connect the negative cable to some metal part of each vehicle, such as the engine. Be careful of the fan blades on each car. Let the donor car run for approximately 15 minutes to put a slight charge in the battery on the Corvette before you attempt to start it. Start the Corvette and as soon as it starts disconnect the battery cables.
