I am new to the site and this is my first post so bear with me. I hope this is not too long but I need help and I want to give all the info.

2000 Chevy Suburban 2500 - has worked great for 9 years - about 140,000 miles
My son has the truck at college and I am trying to help him from a distance. Here is what happened.
1. vehicle stopped running while out driving
2. 72 month Napa battery checked "dead" after 14 months - got another warranty battery
3. My son installed the battery with me on the phone.
4. He said that the keyless did not work - while installing the terminals he said that the terminal was sparking excessively, the lights were flashing and the interior was making clicking noises - probably the door locks. I told him to turn the lights off as they were set for automatic - this helped and he finished.
5. Vehicle started right up but kept dying if he did not give it gas. I told him to keep it runing and after a bit put it in drive and it kept running. He drove it up to school and parked it. He had to lock manually since the keyless was not working.
6. Next day he opened the door with the key and the alarm went off and he could not stop it. It finally stopped and he drove to baseball practice and the alarm went off while driving.
7. That night he went to the bank and lost the headlights, windows would not work, interior and dash lights went out and the truck died. It would not start. He left it and walked back to school. I have not heard back.
8. With all the electrical items going outand then the truck stalling I was thinking alternator but would the computer not send a message in advance if the alternator was bad?
9. What do you guys think? Any solid experience?
10. The truck is in Whittier California in the event that someone reads this from Whittier.
11. If I can't get some definite good info then I will need to fly there and get it fixed since my son does not have a lot of car experience to trouble shoot. If I tell him to take it to a shop that could end up costing a small fortune.

Thanks
George
