You can get it tested free at most auto parts retailers.

How old is the battery? Usually when you get a sudden "won't start" scenario it is the battery. I've had that before and had to carry a new battery 3 blocks

It did, it was also about 90 outside that day. Kinda miss that truck, kinda glad I don't have it anymore...was my old '92 f150.

My money is new battery fixes your issues. Usually they get to that 5-7 year mark then just crap out on ya.

I noticed the same thing with mine and I ended up replacing my battery. I have a unit that boosts/charges/tests batteries as well as alternators and my battery turned out to be defective. I upgraded to an AGM battery for a considerable cost. I'll post a thread about it shortly.
