H2 Won't Start, but Weird issue...

[Goalkeeper]

Has anyone seen anything like this before:

3 Weeks ago: I try to start my truck, after driving about an hour, and it wont start. Weird thing is, I have all power, windows, radio, lights, it all works. Then I try again in a minute, and I get NO power. Now I'm stressed b/c the sunroof and all 4 windows are down.

I wait a few minutes, try to start again = nothing, but I have power again and can close the truck up. So I jump it but it won't start, same issue, all electric but nothing (no clicking or anything) when I try to start. So I let it sit connected to my wife's car for about 10 minutes and try again: Starts right up.

I go to the local auto parts store and they lend me a tester. The charge is great and the Load is perfect. I then get a mechanic (non-dealer) who I trust implicitly and he can't find anything wrong.

Since then, it's bee running fine. Until yesterday. Same issue, I was driving it earlier in the day and then later on, I can't start it. Each time I try, there's full electric, no clicking like its a starter/alternator. I try to jump but same issue - all power, no starty.

So, I'm left with getting it towed to the dealer tomorrow and let them check it out.

Sorry for the long winded post...

Thanks in advance for any help, advice, ideas!!!
