Engine woes

[Ohearchai]

Was running fine, had a bit of an exhaust by passenger side manifold/down pipe joint. On the freeway this morning, 10 miles in, she starts surging and sputtering, eventually dies on the side of the road. Was able to start her again, ran rough for a few miles, eventually died and wouldn't start again. Where do I start.
Thanks.

On a TBI I would start with the fuel system.
Does the pump run when you key it on?
If the filter has not been changed recently, change it.
Do the injectors fire?
If not, it could be the ignition module in the distributor.

My 1995 has presented me with all of these problems at one time or another.
