The truck has 120,000 mi. auto trans. Had new plugs @ 90,000mi. This problem happens very intermittently any thing from -20 to 95 degrees, usually it will crank well but refuse to fire or fire intermittently untill it starts. The last time it acted up, once it started, the theft light light was on for the entire key cycle. It generally runs somewhat roughly once it does fire but not always. One time it ran rough for two hours of interstate driving and several key cycles afterwords. It had a fuel filter at 90,000 but that means very little. One other thing I will mention, but this vehicle has done since practicaly brand new, it will crank hard intermittently (like advanced timing). I don't belive the timing thing has anything to do with the no start.

Re: 1998 s-10 2.2l intermittent hard start
Because you said it sounds like timing problems i may have an idea. i dont remeber if these have a distributer? but its common for the distributer on the newer GM trucks and i dont know why but its like the spark jumps around inside causing incorrect firing order when trying to start and just gets worse and worse. remove and inspect for build on on rotor and tabs on distributer.
and get back to me with problem

Timing 6 degrees before TDC vacuum hose disconnected from vacuum advance. Idle @ 600rpm auto trans. and 700rpm
for std. trans. Plug gap .035 non HEI ignition, point dwell 28-32 degrees or .019 gap with feeler gauge on high lobe point open. Timing can vary a few degrees depending on cam and fuel. Also point setting changes timing. Go back and check each reading as you change one the others change. (example: increase timing, rpms also go up) All settings made with vacuum hose off advance and plugged.Hope this helps good luck.
You could try the linkage cable from the shifter(under the hood). It could be alot of things. Is it auto or manual trans? And what do you mean by wont shift? Is the the shifter moving from P,R,N,D, ect... or the transmission is not shifting into a higher gear?
This is an electrical problem, I had this last winter where the car was restarting or the starter was not disengaging. The problem was with the starter. the contacts that meet the plunger in the starter were grooved severely and binded with the contacts.
I had to replace the contacts inside the starter.
THIS CAR USES WHAT IS CALLED AN INTERFERENCE ENGINE, THIS MEANS IF THE BElT BROKE WHILE DRIVING YOU HAVE BENT THE INTAKE AND EXHAUST VALVES, VERY REARELY THIS DOESN'T HAPPEN SO PUT A NEW BLET ON AND CHECK THE COMPRESSION, IF U HAVE NO COMPRESSION OR LOW YOU WILL NEED TO HAVE THE CYLINDER HEAD REMOVED AND THE VALVES REPLACED, U MAY ALSO HAVE BROKEN A PISTON CROWN AS WELL, THE NORMAL CHANGE INTERVAL FIOR THE TIMING BLET IS 120,000 MILES, SO IF IT BROKE BEFORE THAT CONTACT CHRYSLER THEY MAY PROVIDE SOME ASSISTANCE WITH THE REPAIR COST.
Replace the timing belt, and the water pump is there is ANY evidence of leagage. Replace the plugs and the wires. Replace the coolant, the oil and the Auto trans fluid. Replace the air filter. This is the MINIMUM required service.
Whtat is happening is the engine temp is too hot and is probally sending a code to trans computer and car shifts eratically tthe normal temp is 180 degrees and if it gets too hot the engins a code to trans computer
