Cruised about 50 miles today in the hot heat. Everything seems to be fine after lunch on the way home. Then suddenly the dreaded stalling out at a red light. Would crank but not run. Rolled over to the side of the road, then pushed it into a parking lot. Did I say it was hot out today?

Opened the hood and thought about it while cooling off. My first thought, crank sensor. I have a spare with me. Looked at the sensor in the car, could not see it for the bright sunshine all around. Skip it for now.

Swapped out the RCM with a spare I had, no change. Put the old one back in. I could hear the fuel pump run with key on.

Tried one more time and now the battery dead! Won't crank, just click, typical sound of low battery or bad connection. Checked what I could, all looks good. Called my son for a jump-start. Now about 1/2 hour my son shows up, car cooled off, starts right up with a jump. Alternator charging at 13.9 / 14.0.

Make it within a mile of my house and quits again. Coast into shade and wait again to cool off. I still don't want to change out the crank sensor with a hot engine. Sat there for a while and police show up to help. Again after just several attempts, car acts like a weak battery. I told him I needed a jump but I kept the conversation going so the car could cool off.

Finally the jump box comes out the car fires right up. We get home safe and sound. Let the car cool off. I check my records that the Interstate battery is 7 years old! Wow does time fly!

So my plan of attack for tomorrow - Replace battery regardless of test results, replace crank sensor with OEM I still have in the package, and clean and check ground cables.
NO check engine light or codes.

I will keep you posted as time permits. James
