won't stay running

Frustrating situation. So, there could be potential concerns at just about anything electrical. Because it runs then quits, I'm thinking air intake - such as mass air flow or manifold pressure sensor. Idle air control valve. Things like that. However, the worse thing could be an issue with the PSOM (programmable speedometer odometer module) in the instrument cluster, that can definitely casue driveability issues. If your cluster got a jolt, it could be causing issues. Tough diagnosis.
