the blazer keeps dying while driving and sometimes i cant even start it. it can still be driven but to worried it die and not start back up. a hamster has lived in the engine for a while before finally catching it. any idea what the problem is? would be greatly appriciated. it had a complete tuneup i think that includes fuel filter and the hamster chewed up some wires and the shop cant figure it out.

Fuel Filter? Has the fuel Filter ever been changed? You need to do it any way, why not now? This sounds like your problem. Can you be more specific?

Anything ever been tuned up?
