When I start my car for the day, it starts just fine. If I try to start it after I turne it off for like 5 mins it will give the good old sound of a dead battery. However, 10 mins later, it starts like a champ again. At first I suspected that the starter was suffering from heat soak, but if I turn it off after starting and 5 seconds later start it, it will start fine... but 10 seconds after that, I have to wait for the 15 mins to start again... the odd part is that if I hook up someone to jump me, it works fine....

Thanks

F15,

If all the electrical connections from the battery are in good condition, I think your original presumtion is probably correct. The starter may be developing a heat-related failure.

The fact that is will start within a few seconds of being shut off is not unusual. The internals get tighter when the oil stops flowing, and the starter actually gets a little warmer in the first few minutes after a shutdown.

You don't come over the fence "hot" then immediately shut down your P&W F-110 fans without a little water spray first, do you? (Cracked turbine blades can wreck you entire day.) The same is true for your piston engine groundcraft, but you probably don't have the luxury of water spray to cool it down before turning it off.

A new starter/solenoid designed for higher starting torque should solve most of your problems.
