Electrical System Problems of Mazda B-series Truck

My truck sat for a while I charged the batt. I drove to the landfill in tehachapi CA. It ran fine. I unloaded the trash the engine idled for 30+min. The landfill had debris on the ground. The truck ran fine back to town. I had 3/4 fuel. I decided to fill up at the loves gas station I filled it all the way 2 clicks I think. I started up the truck after fueling it ran terribly I had a flashing check engine light. I drove home 2milles when home the truck was on ?? fire!! I turned off engine. Put lots of h20 on fire. Disconnected batt put more h20. I don't know if it started at gas station or in between. I can ask neighbors. The fire was under the driver's seat under neath the truck. I don't know if it was damaged by debris at the dump there was lots of crap on the ground. It has not been inspected yet. I have not started any repairs. No police report. No damage to any one or property. (except my truck)it is in my driveway and can be inspected there or towed. No pictures but I can take some. I am glad it didn't cause the gas station to go up in flames. Yes I have it insurance.

The electrical system shut down while I was driving, turning off air conditioner, radio, interior lights, and turn indicator. The dash lit up abs, airbag, and cruise control indicators. When I stopped, I turned off the engine and turned the key to power without starting engine and found the electrical working again. I tried driving again and the electrical system worked for a short time and went off again. When it first happened, I was driving straight on a city street.
